sister act off the top of my head, and because someone said Whoopi just above me here, so I thought of it.... I am sure there have been worse I suffered through, but just cannot think of them right now.
not crazy about too many musicals, either.....and funny, since I love music so much...but not films where people are singing their parts.
Loved Phantom of the Opera and Me and My Girl on Broadway, though....just to give a thumbs up to those....and they were live, too....but the musical movies....I tend to avoid if I can. Might like Phantom as a movie, though.
So many bad movies to try and remember.. But I'd say Santa Claus Conquers the Martians would have to be near the top of the list.
Just watched Deathbed a few weeks ago. Birdemic is also pretty terrible. It's a toss up on which is worse...
Beyond The Black Rainbow and Subconscious Cruelty I think I hate them because they are movies that piqued my interest, then made me frustrated and then finally made me angry because of how pretentious they were.
