As I mentioned on TST.com, I'm a little apprehensive of the director change. For one, each director has a distinct style, and it's always a little unnerving -- for me -- when a new director starts on a franchise. I hated it when Singer left X-Men and I REALLY hated it when Christopher Columbus left Harry Potter. Sometimes directors change just little things or they go in a whole new direction and you can SEE it. It kind of messes with the continuity.
I don't think I've seen much of Chris Weitz's work. I did watch The Golden Compass, though, and I LOVED it. Until I read the books. I understand that the subject matter was very sensitive and that they altered some of the references to Catholicism to make the movie more family friendly. However, they changed a LOT of things unnecessarily. Character names, they switched scenes around, they changed the characters THEMSELVES... And maybe I should be blaming that on the writer. I'm not sure. I just know that as a movie, I loved it; as an adaptation, I was repulsed.
But since Twilight isn't even remotely as controversial as His Dark Materials, maybe everything will work out. The graphics, for one, were AMAZING in TGC.
(On a side note: D: I finally get my computer back tonight, only to find out that tomorrow, the boards will commence their brief hiatus.)
