The voyeuristic “killer’s POV” used extensively in retro slasher films is taken to a new campy level in The Deep Queer Massacre — merging cam-culture with the masked-maniac trope we’ve grown to expect in the genre. Set in a secluded vacation home, a troupe of horny gay boys sporting short-shorts and super-soakers are picked-off one by one in chic, B-movie style — paying homage to the classics that’ve cum before.
