comparison to mischa
Emma is a much better actress than Mischa though. With Mischa, it is absolutely true about wondering why she's there. How the hell is that Mischa Barton a star on OC? The chick who plays Summer is a much better actress and much more interesting, so why all the fuss about Mischa?
But with Emma, she's a great actress and, unlike Mischa, quite pretty, so I can't agree with the comparison. I think Emma belongs where she is.
