1. Shock Treatment (1981)
Corsets. Transsexualism. Sing-a-longs. Yes, its The Rocky Horror Picture Show (1975). A movie so bizarre it failed any attempt at description and could only have been the cult classic it became. The sequel features the residents of the town of Denton as the audience of a television quiz-show whose only purpose seems to be to send the original characters to Dentonvale Insane Asylum. Nobody has EVER seen this film. EVER. But if youre the sort of person who finds themselves at small independent cinemas after midnight wearing fishnet stockings and brandishing a water-pistol, you will probably LOVE it.
