Candidate passages:
"American Hustle" received critical acclaim upon its release.
The cast received praise for their performances, notably Adams and Lawrence.
Review aggregation website Rotten Tomatoes gives the film a 93% rating, based on reviews from 240 critics with an average score of 8.2/10.
The site's consensus reads, "Riotously funny and impeccably cast, "American Hustle" compensates for its flaws with unbridled energy and some of David O. Russell's most irrepressibly vibrant direction."
Metacritic gives a score of 90/100, indicating "universal acclaim", based on reviews from 47 critics.
Christy Lemire awarded the film four out of four stars, praising David O. Russell's directing and the relationship between Irving and Sydney, as well as Jennifer Lawrence's portrayal of Rosalyn.
She writes: "For all its brashness and big personality, "American Hustle" is a character study at its core—an exploration of dissatisfaction and drive, and the lengths to which we're willing to go for that elusive thing known as a better life."
Richard Roeper of the "Chicago Sun-Times" gave the film an A+, especially complimenting Bradley Cooper's performance and stating that "American Hustle" was "the best time I've had at the movies all year."
He later named it the year's best film.
"Time" magazine's Richard Corliss wrote, ""American Hustle" is an urban eruption of flat-out fun — the sharpest, most exhilarating comedy in years.
Anyone who says otherwise must be conning you.
"Peter Debruge of "Variety" was critical of the film, calling it "a sloppy sprawl of a movie" and complaining that the improvisational performances overwhelm instead of adding to a coherent plot."
He also went on to write that it "makes your brain hurt — and worse, overwhelms the already overcomplicated Abscam retelling at the center of the film."
Katt Williams: American Hustle, also known as American Hustle: The Movie, is a 2007 comedy film directed by Brit McAdams, and written by Brit McAdams and Katt Williams.
The film was R-rated for its sexual content, drug use, and profanity. 
The movie received positive reviews from the Hollywood Reporter and Variety. 
Entertainment Weekly (sometimes abbreviated as EW) is an American magazine, published by the Time division of Time Warner, that covers film, television, music, Broadway theatre, books and popular culture.
Different from celebrity-focused publications like "Us Weekly", "People Weekly" (a sister magazine to "EW"), and "In Touch Weekly", "EW" primarily concentrates on entertainment media news and critical reviews.
And unlike "Variety" and "The Hollywood Reporter", which are aimed at industry insiders, "EW" targets a more general audience. 
Critical reception for "Vampire" has been mixed.
Much of the film's criticism stemmed from its length, as media outlets such as "Screen Daily" and the "Montreal Gazette" felt that it detracted from the film's overall story.
"Variety" praised Iwai’s "fastidiously composed scenes of ritual bloodletting" as one the point where the film "springs to life", but remarked that the film had a limited appeal.
"The Hollywood Reporter" had a similar opinion in their review, with the bottom line reading "Artsy but alienating quasi-horror film offers a non-supernatural alternative to Count Dracula."
"io9" was more positive in their review, stating "Fans of more traditional vampire fare may not find what they’re looking for in this piece, but anyone who has seen Iwai’s other work, especially his masterpiece of oddball suspense "Pikunikku (Picnic)", will be right at home with his American debut."
Reviewers for "Twitch Film" gave predominantly positive reviews, echoing "io9"'s sentiments and stating that "for those not turned off by some graphic violence and a whole lot of artistic license, there is a lot to like about this portrait of a killer more empathetic than psychopathic."
