Don't watch movies I expect to hate, really, but closest thing I can recall at the moment was yesterday when I finally got around to watch Taxi Driver, with Robert De Niro.
I didn't have much expectations. Just wanted to see De Niro on a mohawk, but the movie turned out to be more than awesome. Sucks that we only got to see the mohawk for a little bit in the ending.
He should've gotten an Oscar nomination for that movie.
