“The Slumber Party Massacre” is in a league of its own, even by 1980s slasher standards. Written originally by Rita Mae Brown as a feminist satire of “Friday the 13th” and its conventions, yet directed through a sleazy male gaze by female director Amy Jones, the whole movie is completely bonkers. It actually helps to know this movie’s strange history before watching it, because it explains why what you’re watching is so off-beat and atonal. The feminist themes are handled with the subtlety of a sledgehammer, but that’s because the production company doesn’t seem to have understood the comedic roots of the screenplay, and ultimately the whole thing has no counterpart in strangeness (OK, maybe 1983’s “Sleepaway Camp” comes close). It’s worth watching just for the “WTF” factor, but I recommend some altered states and snappy friends to accompany your viewing.
