The reason is that if wewe look closely wewe can see that Bella and Kirsten act the same way the are both quiet,shy,and hardheaded.So inayofuata time wewe see twilight think about for just dakika and say to yourself"they both act alike not just because she plays her but like in the books!" ~PLEASEZ GO TO Youtube 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 wewe just see how well they go together in the story and in real life.
And this is a matter of OPINION. So wewe didn't like Kristen as Bella. Tons of other people DID. I think she did a great job. And besides, I doubt wewe 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 wewe 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!!!
