It seems to preserve the atmosphere of the Silent Hill games, at least with the whole, "weird lighting, girl whispering" business, but it depends on how Roger Avary's script and Christophe Gans directing come together - and we don't see much of a hint at the quality of either from the quick teaser. Looking through the cast list, Boromir (the actor who played him, Sean Bean) is in the flick, so it can't be all bad.
