"Not funny enough, or dramatic enough, or sexy enough, or bad enough, to qualify as entertainment in any category."
That's Leonard Maltin's verdict on Striptease (1996), a Demi Moore vehicle that proves not all bad movies are uproarious fun. Anyone who enjoyed Plan 9 From Outer Space or Troll 2 would go out of their minds if locked in a cinema during a screening of this turkey.
Maltin's words also serve as a good definition of what makes a picture truly bad as opposed to enjoyably bad. Plan 9 may be a failure on every conceivable level, but it fails upwards (so to speak), whereas Moore's film is so flat and forced you'll check your watch every two minutes...
