Richard O'Brien's Shock Treatment landed with a dull thud on release in 1981; this semi-sequel to Rocky Horror didn't please that film's rabid fan base and failed to find one of its own, hampered by one of those seemed-like-a-good-idea marketing concepts, screening the movie only at midnight.
Seen three decades on (!*), it actually looks both fabulously proto-80s and really rather clever. Despite the lamentable absence of Tim Curry, having Barry "Edna" Humphries around in what looks like a key role must provide some diversion, and anything that give us another glimpse of Little Nell really ought to be worth a look.
*Geez we're all getting old, fast, no?
