Input: Consider Input: What Causes Zombies? . A sailboat arrives in New York Harbor. It seems abandoned but a coast guard member is killed by a man on board. The man is shot and falls into the harbor. The boat belongs to a man whose daughter is concerned about him. She and a reporter hire a boat to find her father. Their destination is an island said to be cursed. The boat they hire is run by a young couple. Along the way the couple do some diving (she is topless). She is scared when she sees a man under the water who attacks a shark and tries to eat it. She is very upset and somehow loses the rest of her suit when removing her tanks. The Continue to the island which is just a short distance away. Once on the island they discover researchers looking into a phenomena where the dead rise to attack the living. Legend says it is the work of voodoo but the lead scientist is convinced there is a medical explanation. Unfortunately the missing father has already died but at least now it is known. But soon the zombie trouble gets out of control as cemeteries give up hordes of the walking dead. In the end, only a few manage to escape the island to head back to civilization. They keep one zombie as proof that they are not crazy. This is one of the better zombie films although the final battle is a little odd as zombies seem to appear out of nowhere inside buildings. That aside the story builds nicely with the multiple plots weaving together smoothly. There is plenty of nudity in this one and plenty of gore, although somewhat tame by today's standards. The acting is reasonable for the effort and special effects are decent. I enjoyed the ending which I gather was supposed to be a shocker but which I predicted from the beginning. My guess is that most viewers will get too caught up in the rest of the movie to think that far ahead, or so the producers hoped. If you like zombie films you will have to check this one out

Output: POS

Input: Consider Input: PLUNGE INTO OBLIVION . DARK DESCENT is about as exciting as watching someone make banana pudding. Filmed in Czechloslovakia, most of the actors and crew's names end in "v". Which wouldn't be so bad if they could at least ACT. Dean Cain, he of Superman fame, bullies his way through the mess, chewing his gum, and wincing after he gets shot in the leg. Scott Wiper who plays his jealous comrade mercifully disappears once he quits, but the movie never says what happens to him. The movie starts off with Cain and Wiper (sounds like a law firm, don't it?) facing some really nasty guys who are obviously attacking the women in this undersea mining plant. Nothing is ever explained as to why they are doing this, but Cain kills them all but one, a nasty guy who plans revenge. Meanwhile, many of the crew members are committing suicide, and Cain is investigating. (Excited yet?). Of course, it all culminates in a kind of underwater HIGH NOON when the bad guy who promised to come back, does so with two other goons, and chase Cain around the plant for a while. There is nothing exciting about any of this, as the direction is wooden and the acting abysmal. Try THE ABYSS or GHOST SHIP or any other undersea film, and you'll do much better than this waste of celluloid

Output: NEG

Input: Consider Input: Not Another Teen Movie!!! . Milo Ventimiglia (Gilmore Girls, The Bedford Diaries) stars as Zack Harper, a kid who helps out his friend Kyle who is in a bit of a rut. Kyle was challenged by a senior to do the Dirty Deeds. The Dirty Deeds (there's 10 of them) are just random things on a piece of paper the person has to accomplish. There's also a record that has never been beating before. So, Milo sets out to do the Dirty Deeds and there's also a party being thrown at a house where they keep a scoreboard of how many Milo has done. Not Another Teen Movie!! Just had to say that but its bascially what it is. In American Pie you had Jason Biggs doing the pie and in this, well Milo Ventimigla enters a bag of whole wheat bread (if you know what I mean). Milo helps the film but nothing is special about this movie. More moronic characters. My advice is watch it (Unrated or not) once and the decisions are up to you. Also starring Lacey Chabert (Not Another Teen Movie, Mean Girls) of course, Mark Derwin (One Life To Live, Heist), Zoe Saldana (Drumline, Pirates of the Caribbean), Panso Gorson (South of Nowhere, Dear Wendy), Billy L. Sullivan (My Life, Little Big League), Ray Santiago (Meet The Fockers, Pinero), Todd Zeile (King of Queens, SNL), Michael Milhoan (American Gun, Pearl Harbor), Erin Torpey (Crescendo, One Life To Live), Arielle Kebbel (Aquamarine, Be Cool), Dave Power (Frailty, Boston Public) and Charles Durning (The Final Countdown, Rescue Me) for some odd reason that I dont know why. What does the Unrated version have to offer? Female Nudity what else?!
