I don't know what made it different from the other slashers, but this was amazing! Warning: there are graphic anal sex scenes as well as regular. I am not sure, BUT HAVE HEARD, that the unrated version shows penis entering vagina up close. Many sex scenes, in one, the guy keeps tell the girl she has perfect t*ts, while the guys girlfriend knocks on the door outside. Nudity is shown many times in sex scenes and in a porn magazine. Violence is disgusting, intense and disturbing. Machetes, screw drivers, you name it, they have it. Lots of alcohol/drug use. A person is shown drinking beer from his shoe, during a drinking game. Marijuana is discussed, and when a guy looks for a place to pee, he sees a marijuana leaf, follwed by his friends dead, bloody body. During sex, girl wants guy to check if they are being watched, and he says "I'm not going out there with a b*ner" girl says: if you don't your not getting any for a week/month. (I forget how long she said.) still, my bloody valentine has more graphic nudity than this, (that one shows a vagina.) and overall friday the 13th was awesome!
