I don't think that a video game has been adapted in such a manner before. It's as if you're watching the video game in front of your eyes. And although I only have played one Silent Hill, I know that they achieved to transport the game on your screen (theatre) literally!!
But that is also the downfall of the movie (imo). It is very compelling in the beginning, but when it reaches a certain point (let's say the middle of the movie), the scares don't work anymore. The effects still remain great, but I'm just not feeling it. As a game that would work, because you're actively involved, but as a passive viewer, you get bored. So the best adaptation yet, shows us that there is more to the adaptation process, than filming a game ...
