Mystery Science Theater 3000: The Movie
A regular episode of the MST3K T.V. show is 2 hours long, including commercials. Without the commercials, I suspect an episode is probably about 80-90 minutes long? The big-screen MST3K Movie is only 74 minutes. According to the IMDb, "The TV show's usual density of gags was reduced for theatrical audiences, so that a larger number of people laughing wouldn't cause too much dialogue to be missed." To sum up, I found the whole experience disappointing.
