I'm actually more worried about Kristen Stewart's performance, strangely enough, since I find her a great actress. Now, I didn't mind the acting itself, just the dialogue. I don't know...something about how she delivered her lines/the tone of her voice bothered me. It just didn't feel convincing enough... maybe it's just me? Watch the trailer, and judge for yourselves. Either way, I'm looking forward to the movie!
