There always does seem to be that one rare movie that is so horribly bad that it is good, like once in a blue moon you might come up with something such a The Room that is such as stale, badly done movie that it gets a couple of laughs, and obviously, a good game to be made from it.
Obviously there are those movies that are absolutely sickening to watch, like Disaster Movie, Epic Movie, etc. That is, at some point during the film, embarrassing to watch due to how horribly done it was.
