I agree about expectations. I know I've been disappointed in films because of what I've gone in expecting. I often re-watch them if that's the case because I know I wasn't judging them fairly. I disliked Hatchet when I first saw it because I wasn't expecting a horror comedy, now it's one of my favorite films! Also, just because you know a film is going to be shit doesn't mean it should be exempt from the shittest movies ever made category.
