A curious meditation on the pleasures and terrors of s/m, in which interviews with enthusiasts collide with choice porn clips, Fleisher cartoons, Hans Bellmer poupees and a couple of sphincter-tightening routines.  The results are compelling, this film lingers, never once slipping into hype or deadly cool.’ – Manohla Dargis, Reel To Reel, Village Voice, 1992.
