Lastly, out of interest, how many of the people who don't like Kristen playing Bella are male?
I don't think she'd have much problems with the guys . . . Kristen is so beautiful. That's like asking the girls if they have a problem with Rob playing Edward. The face comes first, then the acting. ahahahaha, in most cases that would be accurate.
But also, keep in mind that recently Kristen has needed a slap on the face and I am sure if Rob was acting as stuck up as her, I would have recommended the slap too (I LOVE ROB just so you know *melts*)
Well, my point is not the fact that guys would like Kristen because of her looks, but that girls would NOT like her for various other reasons.
It has been my observation over many many years of being around the female population (I have 3 males in my day-to-day life - all my family in town are female, and I work in a pharmacy . . . . . . ) that girls will dislike girls until they find a reason to like them, where as guys will like any person (in general) until they find a reason to dislike them.
So, as far as the role of Bella goes, I think no person could have fulfilled the role to the satisfaction of the female fans any better than Kristen does.
I am taking all of the criticism of Kristen with a grain of salt for this reason - the fandom is mainly girls, and as a general rule, girls dislike other girls by default. The other reason i am taking it with a grain of salt is because when it comes to propaganda and "who said what", the press in general can't be trusted, because they make money out of headlines and sensationalism, and the entertainment media especially can't be trusted for this reason.
Never mind the fact that she did a great job, her portrayal of Bella is believable and endearing, and her half-sentences and mannerisms (which other people have criticised) are very much the behaviour you would see in adolescent girls, especially those who are confounded by a profound love for someone they've only just met.
