I seriously can't believe I was the only teen on this site who reviewed this.It's an absolute waste of time.I watched this movie in the cinema with my dad and I was like the only kid there Lol.Guess others know how to spend their time wisely.This is an extremely mature film not to be viewed by anyone under the age of 17.Tons of gore,flesh,nudity,and who can forget,the language?You wouldn't want your kids to turn into rotten sailor mouth beings or much worse,become serial killers when they grow up do you? Update:Rated R for strong bloody violence and gore,strong sexual references and aberrant behavior.What do you expect from a movie about a bunch of people trying to commit the "perfect" murder?
