Is there a movie that you dislike, but can't help watching whenever you come across it on TV?

This Q was based on Symbeline’s Question about learning to appreciate a movie that you previously disliked. This Q has a bit of a different take. You think this movie is crap, but you still watch it and you don’t know why.

Of if you do know why, please let me know and maybe it will give me some insight into why I can’t pass by on the original Dirty Dancing (it’s so bad) or It’s a Wonderful Life (probably even worse).
