I actually enjoyed the first Silent Hill movie quite a lot. In my opinion, it's the best video game-to-movie adaptation. Obviously, it's not perfect, but oh God is it nowhere near Revelations. What were they thinking with that one? >_<
Minor off topic. Have ever seen the fan-made Silent Hill movie on YouTube? It's around 8 min. It was pretty decent work. Of course, they felt the need to shoe-horned Pyramid Head again lol. Aside from that, it had some highlights. Check it out if you haven't: https://www.youtube.com/watch?v=nFeKZcONmt4.
