Twilight- a saga plagued by anti-feminism?

        In theaters I recently saw a trailer for the next film in the twilight series and it got me thinking; the roles in the past three installments of the films portray Bella, the main character, as the protected 'object' of Edward, a vampire, and Jacob, a werewolf.

a.  b.

         These installments have portrayed Edward and Jacob as the protectors of Bella, and they fight over her; this concept worn down to basic terms is relatively primitive- two men fighting over what they seem to see as their 'possession'. Both Edward and Jacob are more powerful than Bella due to their supernatural traits. Bella is portrayed as quiet and curious, but once her life becomes intertwined with the lives of Edward and Jacob, she almost becomes dependent on them for her survival. In other words, she needs them to care for her. In photo (a), Bella is protected by Jacob, and in photo (b), Edward has his hand around her arm and is acting as a protector. The only way that Bella becomes powerful is because Edward bites her and makes her immortal and strong, she does not and cannot achieve this level of strenght independently. Also, Edward and Jacob both save her life on multiple occassions, but never, I'm pretty sure, does she come to their rescue.

            However, this story could have another side to it. Edward helps Bella become stronger in the last installment (not without Edward, of course), so he does empower her. When Bella wants to become a vampire so she will be the same as Edward, he tells her that he would care for no matter her form, so he is not trying to fundementally change who she is. But which is it- empowerment/acceptance of who she is or Bella as the simple object of Edward and Jacob?
