From the Onion:
Bella never comes off as all that bright, caring, or independent. [S]he wanders through showers of praise and adoration acting generally bored and uncomfortable, accepting all the love as her due without ever comprehending the value of it. She doesn’t have to do anything, beyond being barely capable and not immediately put off by learning that the guy she’s dating likes to break into her bedroom at night without asking permission. For all her talk about being the “strong” woman, Stewart is essentially passive. Good things happen to her because she’s there.
