I remember going to see the Departed on opening weekend and felt a little disappointed. It was a good movie, but with the director and all the great actors, I think my expectations were too high.
Sometimes I think great movies come about when you aren't expecting them. My wife dragged me to see Water for Elephants a few months back. I was dreading seeing it. A love story with Robert Pattinson and Reese Whiterspoon - ewwwwwww. But I surprising enjoyed it more than about anything I've seen at the movies in the last year.
It must have been low expectations. It might not have been as good if I expected better. But it was kinda a cool little story and well acted.
My wife made me see another Robert Pattinson movie Remember Me about a year ago and it was pretty good too given my low expectations. Maybe that guy's a decent actor when he's not in Twighlight??? Or maybe Twilight set my expectation for him through the floor. Who knows?
Whatever it is, I always feel a little disappointed when I'm super excited about a movie.
