Is your opinion based solely on how she looks?
My opinion of her in the role - primarily. I was disappointed when I saw the first movie and that was who they chose.
My opinion of her overall - no. As a woman, her appearance has no real impact on my like or dislike of her overall. While the grunge thing is something I really don’t get; her snarly attitude is why I dislike her overall. If you hate having fans, and a lack of privacy, perhaps acting isn’t the best career choice, especially acting in tween romance movies.
