In some sense, Shivers, a venereal horror movie that invites you to track the vectors of sexual intercourse among a group of apartment-dwellers, is a parody of a soap opera where the point is who is sleeping with whom. It's also a spit-take on those sex-ed hygiene films that try to frighten teenagers into abstinence. Set almost entirely in a Montréal apartment complex and photographed in a jaundiced palette that leans towards yellow-green, it's about the proliferation of parasites that make their way from body to body by a variety of sickening means, transforming their hosts into insatiable sex maniacs.
