How do you spell kinky? Michael Raven. The director known for his superslick, cable-ready features, takes a decidedly off-beat twist in this darkly fascinating series of vignettes exploring the shadowy side of sexuality. But the emphasis is on visual style. Don't despair. You'll still get your dose of the kind of sex Raven is known for, couples in the throes of passion, a multi-racial cast to keep you glued to your tube, and plenty of studs. Kamiko, Sin City's most recent contract girl, makes her Raven debut in Erotica, and makes a nice match to Raven vet Charmane Star.
