The reason is that if 你 look closely 你 can see that Bella and Kirsten act the same way the are both quiet,shy,and hardheaded.So 下一个 time 你 see twilight think about for just 分钟 and say to yourself"they both act alike not just because she plays her but like in the books!" ~PLEASEZ GO TO youtobe AND CHECKOUT THE BREAKING DAWN PT.2 TRAILER!~
Because they couldnt find a better Bella. She's pefect for the role. Without her Twilight wouldn't be the same. Cant 你 just see how well they go together in the story and in real life.
And this is a matter of OPINION. So 你 didn't like Kristen as Bella. Tons of other people DID. I think she did a great job. And besides, I doubt 你 could've done any better as Bella.
I personally think they chose Kristen because Catherine Hardwicke directed the first movie, and to me Kristen is the kind of actress 你 see in alot of Catherine's movies. Also, this was around the time when Kristen was getting recognition for "Into the Wild". I dont think Kristen is a bad Bella, but I agree that she was not the best choice. I would have like to have seen Emily Browning, who they say was Stephanie Meyers' first choice, but we got Kristen, and I dont think she is too bad.
BECAUSE THEY CANT KRISTEN STEWART IS BETTER THAN ANYONE FOR THE PART OF BELLA SHE IS SKINNY AND STUNNING!!!!!!!!!!! SO FUCK UP!!!! KRISTEN IS THE ONLY PERSON WHO CA PLAY BELLA IT'S NOT POSSIBLE TO FIND ANOTHER ONE!!!
