I decided to make a much easier list to find good movies to watch. I left out those that I wouldn't suggest on a night when you want something rather good. You will have to go to the actual posts to find the ones that I suggest avoiding and the ones that I would only suggest if you don't have anything better to watch. I also have a list for Asian movies to watch, you can find it here.
