Psychedelic - yet boring - gore (even if we don't get to see much)! The premise isn't oringinal at all, it's actually repetitive, but, somehow, it promised to be a hell of a fun ride... but it wasn't... Not scary or provocative, it's just another erotic teen demoniac slasher genre of movie, with weak plot and characters, trying to achieve what the original "Evil Dead" (clearly this was inspired by that one) did.
starts good & creepy. gets boring, very boring. but nonetheless good time machine into the 80's :)
