Is she getting too pretty? In the third movie, she looked really good, so I'm curious to know why the guys aren't all after her, and why it takes Ron until he sees her at the ball to realize he likes her.

In the book she has no control over her hair at all, so why does she in the movie? Another thing I was wondering was why she said that one line in the third movie... something like "That's what my hair looks like from the back?". That is SO not a "Hermione-line"
