I really liked the Silent Hill movie as well. I don't understand all the hate it gets. So it didn't follow the story from the game. That's a good thing, I prefer a new story then watching a movie try to adapt hours of gameplay into a 2hour movie. It won't work and you'd lose out on a lot of things that made the game great.
Also besides that I think Silent Hill would have done better if it wasn't spouted as a video game movie. Me and my friend are in agreement that it is one of the best Horror films made within the past 20years. All you get now a days are Gore/Slasher and shock horror. But the best type of horror has always been Dread. The fear of the unknown and the Silent Hill movie did this extremely well. Yes it had some Gore and Shock(I'm looking at you Garbage Can), but they weren't so overbearing that it took away from that atmosphere of dread. I wish that more horror movies and video games would focus on dread. I don't think it will happen since horror movies now a days just go after that cheap thrill of Shock Horror and Gore since the audience reaction makes good commercials. Not to mention it's easier.
