I really think people involved with movies need to stop saying that. That goes for books as well.
It was said that Silent Hill was very true to the spirit of the game. Gans actually played the damn game, too, and it still ended up displeasing fans and critics(despite, arguably, staying true to the spirit of the game).
I really hope this film is good by both gamer standards and Hollywood standards. We need a good video game movie in order to move on with other projects (such as how Ironman and Batman saved comic book movies). So far we've had either craptastical films (Doom, Resident Evil series, anything by the man who's name we SHALL NOT SPEAK), or things that weren't great but weren't too terrible (Silent Hill and Hitman).
C'mon, Prince of Persia. You can do iiiiiit!
