It has absolutely nothing to do with the games industry. If a good game can be successful with it's story... then that's all you need to work with to make a successful movie, IF you know what the fuck you are doing... have good script writers, good actors, and good DIRECTION.
Thus far, Silent Hill has been buzzing with good words, with decent actors and a strong enough back story it looks to actually be one of the best game-to-movie adaptation. Of course, Silent Hill also has a damn good story which to build off of in the first place.
