Second, there's been a bunch of talk lately about the lack of character development in Bella and also how her relationship with Edward is abusive. One blogger even analyzed Bella and Edward's relationship according to the National Domestic Violence Hotline's "signs you are in an abusive relationship" and came up with 15 signs that point to abuse. In response, someone (and of course I can't remember who at this point) questioned why it's always "Team Edward" or "Team Jacob" and why there doesn't seem to be anyone on "Team Bella." And I think that's because even Stephenie Meyer doesn't want you to be on her team. She wrote a purposefully vague character as a means for her readers to see themselves in Bella and get drawn into the story.
And I guess it worked.
