I have a lot of movies that I love despite a large public saying I'm supposed to hate them. The key is remembering that movie-going is a very personal experience, and the exact set of circumstances that led to you seeing and enjoying/hating a movie are yours and yours alone. I know I have a really hard time hating a movie when I'm on a date with Tyrant, because life is generally groovier with her around. While most of the world forgot about James and the Giant Peach, it ended up being one of my favorite movies ever because I'd had a rough month and it was exactly the movie I needed to see. While most of the world reviles them, I enjoy the latter 2 Star Wars prequels because I saw them for the first time when I was dating, and shortly after marying, Tyrant, so there was a lot of feel-good juice coursing through my blood when I saw them, and watching them takes me back to then.
State of mind is everything when you're seeing a movie. I'm sure if I stumbled on it on TV, or if someone pulled me out of my routine to watch Van Helsing, I'd hate it with the rest of the world. Instead, because I was in just the right frame of mind when I saw it, I find it to be enjoyable. Not GREAT, but not bad by a long shot.
