Movies that turn to shit after 20 minutes

I have to re-post this article from College Humor about a specific category of movies:

Some movies are good, some are bad, some are just ok, and a very select few start out good, get you on board, then slowwwwwly get worse and worse until you finally stop caring about them.”

It’s almost perfect.
