# Dexter (TV series)

Dexter is an American crime drama television series that aired on Showtime from October 1, 2006, to September 22, 2013. Set in Miami, the series centers on Dexter Morgan (Michael C. Hall), a forensic technician specializing in blood spatter analysis for the fictional Miami Metro Police Department, who leads a secret parallel life as a vigilante serial killer, hunting down murderers inadequately punished by the justice system due to corruption or legal technicalities. The show's first season was derived from the novel Darkly Dreaming Dexter (2004), the first in a series of novels by Jeff Lindsay. It was adapted for television by James Manos Jr., who wrote the first episode.
The series enjoyed mostly positive reviews throughout its run. The first four seasons were widely praised, but reception dropped considerably as the series progressed, with the final season and especially the series finale being highly criticized and often cited as amongst the worst of all time. The show has received myriad awards, including two Golden Globes won by Hall and John Lithgow for their roles as Dexter Morgan and Arthur Mitchell, respectively.
The fourth season aired its season finale on December 13, 2009, to a record-breaking audience of 2.6 million viewers, making it the most-watched original series episode ever on Showtime at that time. The eighth season served as the final season of Dexter ; the season premiere was the most watched Dexter episode, with more than 3 million viewers total, while the series finale drew 2.8 million viewers, the largest audience in Showtime's history.
Dexter has continued through an expanded franchise with further series. The sequel series Dexter: New Blood aired from November 2021 to January 2022, with Hall reprising the title role and Clyde Phillips as showrunner. The prequel series Dexter: Original Sin premiered in December 2024, starring Patrick Gibson as Dexter. Further series are in development, including Dexter: Resurrection, and Trinity Killer, a spin-off prequel series.

## Plot

Orphaned at age three, when he witnessed his mother's brutal murder with a chainsaw, Dexter (Michael C. Hall) was adopted by Miami police officer Harry Morgan (James Remar). Recognizing the boy's trauma and the subsequent development of his sociopathic tendencies, Harry trained Dexter to channel his gruesome bloodlust into vigilantism, killing only heinous criminals who slip through the criminal justice system. To cover his prolific trail of homicides, Dexter gains employment as a forensic analyst, specializing in blood spatter pattern analysis, with the Miami Metro Police Department. Dexter is extremely cautious and circumspect; he wears gloves and uses plastic-wrapped "kill rooms", carves up the corpses, and disposes of them in the Atlantic Ocean's Gulf Stream to reduce his chances of detection. Dexter juggles his two personas, recognizing each as a distinct part of himself that must cohesively work as one. He depends on their interaction, as a means of survival and normality. Although his homicidal tendencies are deeply unyielding, as he originally claims (via narration), throughout the series he strives to feel (and in some cases does feel) normal emotions and maintains his appearance as a socially responsible human being.

## Episodes

Dexter aired from October 1, 2006, to September 22, 2013. In April 2013, Showtime announced that season eight would be the final season of Dexter.

Desmond Harrington joined the cast in season three as Joey Quinn; his name was promoted to the title credits as of season four. Geoff Pierson plays Captain Tom Matthews of Miami Metro Homicide. Julie Benz starred as Dexter's girlfriend, then wife, Rita in seasons one to four, with a guest appearance in season five.

### Crew

The main creative forces behind the series were executive producers Daniel Cerone, Clyde Phillips, and Melissa Rosenberg. Cerone left the show after its second season. Executive producer and showrunner Phillips departed the series, after a record-setting season-four finale, to spend more time with his family; 24 co-executive producer Chip Johannessen took over Phillips' post. Head writer Melissa Rosenberg left after season four, as well.
After the conclusion of season five, Chip Johannessen was revealed to be leaving the show after a single run, and Scott Buck would take over as showrunner from season six onward.

## Production
### Exterior filming

Although the series is set in Miami, Florida, many of the exterior scenes are filmed in Los Angeles and Long Beach, California. Many landmark buildings and locations in Long Beach are featured throughout the series. The finale episode's airport scene takes place at Ontario International Airport in Ontario, California.

### Marketing

In preparation for the United Kingdom launch of the series, Fox UK experimented with an SMS-based viral marketing campaign. Mobile phone owners received the following unsolicited SMS messages addressed to them by name with no identifying information other than being from "Dexter": "Hello (name). I'm heading to the UK sooner than you might think. Dexter." The SMS message was followed by an email directing the user to an online video "news report" about a recent spree of killings. Using on-the-fly video manipulation, the user's name and a personalized message were worked into the report—the former written in blood on a wall near the crime scene, the latter added to a note in an evidence bag carried past the camera. While the marketing campaign raised the show's profile, it proved unpopular with many mobile owners, who saw this as spam advertising aimed at mobile phones. In response to complaints about the SMS element of the campaign, Fox issued the following statement:
   The text message you received was part of an internet viral campaign for our newest show Dexter. However, it was not us who sent you the text, but one of your friends. We do not have a database of viewer phone numbers. The text message went along with a piece on the net that you can then send on to other people you know. If you go to [the website] you will see the page that one of your friends has filled in to send you that message. Therefore I suggest you have a word with anyone who knows your mobile number and see who sent you this message. For the record, we did not make a record of any phone numbers used in this campaign.

## Reception
### Critical reception

Metacritic and Rotten Tomatoes scores per season :
* Graphs are unavailable due to technical issues. Updates on reimplementing the Graph extension, which will be known as the Chart extension, can be found on Phabricator and on MediaWiki.org.
Although reception to individual seasons has varied, the overall response to Dexter has been positive. The first, second, fourth, and seventh seasons received critical acclaim, the third and fifth seasons received generally positive reviews, while the sixth and eighth seasons received mixed to negative reviews. While remarking on some of the show's more formulaic elements (quirky detective, hero with dense workmates, convenient plot contrivances), Tad Friend of The New Yorker magazine remarked that when Dexter is struggling to connect with Rita or soliciting advice from his victims, "the show finds its voice."
The review aggregator website Metacritic calculated a score of 77 from a possible 100 for season one, based on 27 reviews, making it the third-best reviewed show of the 2006 fall season. This score includes four 100 percent scores (from the New York Daily News, San Francisco Chronicle, Chicago Sun-Times and People Weekly magazine). Brian Lowry, who had written one of the three poor reviews Metacritic tallied for the show, recanted his negative review in a year-end column for the trade magazine Variety, after watching the full season. On Metacritic, season two has a score of 85 with all eleven reviews positive; season three scored 78 with 13 reviews; season four scored 77 with 14 reviews; season five scored 76 with eleven reviews; season six scored 62 with 10 reviews; season seven scored 81 with seven reviews; and season eight scored 71 with ten reviews.
On Rotten Tomatoes, season one has an 83 percent approval rating with a score of 8.0 out of 10, and the consensus: "Its dark but novel premise may be too grotesque for some, but Dexter is a compelling, elegantly crafted horror-drama."; season two has a 96 percent approval rating with a score of 7.6 out of 10 and the consensus: "The Bay Harbor Butcher secures his nefarious spot among the great television anti-heroes in a taut second season that is both painfully suspenseful and darkly hilarious"; season three has a 72 percent approval rating with a score of 8.3 out of 10 and the consensus: "America's most amiable serial killer has lost some of his dramatic edge, but this third outing continues Dexter's streak of delivering deliriously twisted entertainment"; season four has an 88 percent approval rating with a score of 8.4 out of 10 and the consensus: "The inherent comedy of Miami's favorite psychopath contending with domestic bliss and the unspeakable horror of John Lithgow's Trinity killer coalesce into one of Dexter's most sensational seasons"; season five has an 84 percent approval rating with a score of 7.5 out of 10 and the consensus: "Michael C. Hall's remarkable performance invites viewers into Dexter's heart of darkness in a sorrowful fifth season that explores whether a hollow man can become a real boy"; season six has a 38 percent approval rating with a score of 6.3 out of 10 and the consensus: "Heavy-handed symbolism, an unimpressive villain, and a redundant arc for America's favorite serial killer all conspire to make Dexter's sixth season its worst yet"; season seven has an 79 percent approval rating with a score of 7.5 out of 10 and the consensus: "Season seven represents a return to form for Dexter, characterized by a riveting storyline and a willingness to take some risks"; and season eight has a 33 percent approval rating, a score of 5.5 out of 10, and the final consensus: "The darkly dreaming Dexter lays to rest once and for all in a bitterly disappointing final season that is so hesitant to punish its anti-hero for his misdeeds, it opts to punish its audience instead."

### Popular reception

The season-three finale, on December 14, 2008, was watched by 1.51 million people giving Showtime its highest ratings for any of its original series since 2004, when Nielsen started including original shows on premium channels in its ratings. The season-four finale aired on December 13, 2009, and was watched by 2.6 million viewers. It broke records for all of Showtime's original series and was their highest-rated telecast in over a decade. The season-five finale was watched by a slightly smaller number of people—2.5 million. The show was declared the ninth-highest rated show for the first ten years of IMDb.com Pro (2002–2012). The seventh season as a whole was the highest rated season of Dexter, watched by 6.1 million total weekly viewers across all platforms. The season eight premiere was the most watched Dexter episode, with more than 3 million viewers total. The original broadcast of the series finale on September 22, 2013, drew 2.8 million viewers, the largest audience in Showtime's history.

### Awards and nominations

Dexter was nominated for 24 Primetime Emmy Awards, including in the category of Outstanding Drama Series four times in a row, from 2008 to 2011, and Outstanding Lead Actor in a Drama Series (for Hall) five times in a row, from 2008 to 2012. It has also been nominated for ten Golden Globe Awards (winning two), seven Screen Actors Guild Awards and received a Peabody Award in 2007.
On December 14, 2006, Hall was nominated for a Golden Globe Award at the 64th Golden Globe Awards. In 2008, the show was nominated for a Primetime Emmy Award for Outstanding Drama Series for its second season (Showtime's first-ever drama to be nominated for the award), and its star for Outstanding Lead Actor in a Drama Series. It won neither, losing to Breaking Bad actor Bryan Cranston. In 2010, Hall and Lithgow, in their respective categories, each won a Golden Globe for their performances in season four.

### Cultural impact
#### U.S. broadcast

In December 2007, when CBS publicly announced that it was considering Dexter for broadcast reruns in the wake of the shortage of original programming ensuing from the 2007–08 Writers Guild of America strike, the Parents Television Council ("PTC") protested the decision. When the network began posting promotional videos of the rebroadcast on YouTube on January 29, 2008, PTC president Timothy F. Winter, in a formal press release, again called for CBS not to air the show on broadcast television, saying that it "should remain on a premium subscription cable network" because "the series compels viewers to empathize with a serial killer, to root for him to prevail, to hope he doesn't get discovered". Winter called on the public to demand that local affiliates pre-empt Dexter and warned advertisers that the PTC would take action against any affiliates that sponsored the show.
Following Winter's press release, CBS added parental advisory notices to its broadcast promotions and ultimately rated Dexter TV-14 for broadcast. On February 17, 2008, the show premiered edited primarily for "language" and scenes containing sex or the dismemberment of live victims. The PTC later objected to CBS' broadcasting of the final two episodes of season one in a two-hour block, and to the episodes' starting times, which were as early as 8 pm in some time zones.

#### Association with real crimes

Several comparisons and connections to the TV show and its protagonist have been drawn during criminal prosecutions. In 2009, 17-year-old Andrew Conley said the show inspired him to strangle his ten-year-old brother. In an affidavit filed in Ohio County court, in Indiana, police said Conley confessed that he "watches a show called Dexter on Showtime, about a serial killer, and he stated, 'I feel just like him.'"
In Spain, on July 25, 2009, a man and his girlfriend killed his brother and pregnant partner. The man owned the complete Dexter series DVD collection and the methods used to avoid leaving blood traces were inspired by the show.
On November 4, 2010, in Sweden, a 21-year-old woman known as Dexter-mördaren ("The Dexter killer") or Dexter-kvinnan ("The Dexter woman") killed her 49-year-old father by stabbing him in the heart. During questioning, the woman compared herself to Dexter Morgan, and a picture of the character would appear on her phone when her father called her. In July 2011, she was sentenced to seven years in prison.
In Norway, Shamrez Khan hired Håvard Nyfløt to kill Faiza Ashraf. Nyfløt claimed that Dexter inspired him, and he wanted to kill Khan in front of Faiza, similar to the television series, to "stop evil".
Association was established between Mark Twitchell, of Edmonton, Alberta, Canada, during his first-degree murder trial, and the character of Dexter Morgan. After weeks of testimony and gruesome evidence presented in court, Twitchell was found guilty of the planned and deliberate murder of 38-year-old Johnny Altinger on April 12, 2011.
British teenager Steven Miles, 17, was sentenced to 25 years in prison on October 2, 2014, for stabbing and dismembering his girlfriend Elizabeth Rose Thomas, 17, in Oxted, Surrey. Police discovered Thomas' body on January 24, 2014, and determined the cause of death to be a stab wound to the back. Miles was arrested on suspicion of murder. Miles pled guilty to the crime on September 9. According to Surrey Police, Miles had dismembered Thomas' body following her death, wrapping up limbs in plastic wrap, and had attempted to clean up the crime scene before he was found by a family member. Miles had been reported to be obsessed with the television series Dexter. Miles reportedly had an alter ego named Ed, whom Miles claims made him carry out the murder.
On January 11, 2022, in New Orleans, Louisiana, 34-year-old Benjamin Beale was arrested after police discovered a decapitated body inside a freezer in a painted bus. The body was confirmed, over a week later, to be that of Julia Dardar, a missing mother of two children. They even discovered a grim Dexter profile painting with guns and knives, as this murder was inspired by the "Ice Truck Killer" from the show's first season.

### Games

On September 13, 2009, Icarus Studios released a video game based on the events of season one, for the iPhone platform, via the iTunes app store. The game was released for the iPad on October 15, 2010, and for PCs on February 15, 2011. The cast and crew of Dexter were very supportive, with some of the cast providing full voice work for the game, including Hall. The game has received many positive reviews, including an 8/10 from IGN. No additional content for the game has been released or announced as planned; plans to release the game on the PlayStation 3 and Xbox 360 seem to have been canceled, as no recent information regarding the expansion of the game onto these platforms has been given and both consoles have been discontinued.
In July 2010, Showtime launched Dexter Game On during Comic-Con. The promotion relied on community involvement, part of which required participants to use the SCVNGR applications available for the Android, iPad, iPhone, and iPod Touch platforms to complete treks around the five cities where the game was available. The final trek led to a kill room, where the Infinity Killer had recently claimed a victim. A link was found in the room to a (fake) company called Sleep Superbly, which began an extensive Showtime-maintained alternate reality game that continued until Dexter's season-five premiere. The alternate reality game involves players working cooperatively to help catch the Infinity Killer and identify his victims; several other characters help. During the game, players communicate with the Infinity Killer, among many others. The game spans Craigslist, Facebook, Twitter, and countless unique sites created for the game. Players can even call phone numbers. The characters and companies are controlled by real people, adding an extra layer of realism and the ability for intelligent conversation.
