I do agree with you on one thing: In like interviews she does seem kind of bitchy & "non chalant" like.. "Ew, do I have to be here right now?"
But I read into it, and it's just that she's shy and actually doesn't like being in front of large amounts of people. Haha. So that actually made me feel more for her (Not like, in a weird way..lmao)
But I've always thought Kristen Stewart was an amazing actress, but I do agree with you that in some of her pictures/interviews and stuff she does look "bitchy". But I know it's because she doesn't smile alot...also because of the shyness factor...
I also think she occasionally looks bitchy because she has such strong features and if she's not smiling (like a full teeth smile) her features really stand out and make her look kind of...mean? or intimidating I guess you could say...
i think she's the perfect bella, but i'll be completely truthful..i shouldn't really judge until i see the movie so i'll just leave it as that.
here are some good pictures of her not looking bitchy! haha...maybe they'll help your unsettledness for her as bella.
( i know some pics are her blonde..but it's nonetheless still her!)http://i260.photobucket.com/albums/ii22/yosoylindsay/Kstew/26b8c765.jpg
