Review: A group of people are invited to there high school reunion, but after they arrive they discover it to be a scam by an old classmate they played an almost fatal prank on. Now, he seeks to get revenge on all those that hurt him by sealing all the exits and cutting off all telephone lines.Dark slasher film with an unexceptional premise. Bringing it up a notch are a few good performances, some rather creative death scenes, plenty of excitement & scares, some humor and an original ending.Unrated for Extreme Violence, Graphic Nudity, Sexual Situations, Profanity and Drug Use. Question: is it a positive review?
no
