This movie is one of my new favorites. I went in pretty cold, it's on the list of 50 horror movies you haven't seen, spoiler I have seen several of the movies on the list including Black Christmas, which is one of the few movies I've seen multiple times. Slumber Party Massacre has the same energy to me, with the exception of the nudity. The character's are written very well, they are engaging in festivities, crazed stalker, the police are no help... I highly recommend this movie to people who want to watch horror with a story and character's that have personalities.
