I never understand why people get up in arms about movie adaptations. Maybe it will be great. And even if it sucks, who cares? The game will still be great. The Silent Hill movies were bad, but it doesn't make Silent Hill 2 any worse.
Also, I think Maisie Williams is a great choice for Ellie. Also, I'd vote Josh Brolin for Jole. Maybe that's the obvious choice, but I'd say there's a good reason for that.
