A lot of people criticize Kristen Stewarts acting, but in most of the films I've seen her in, she has taken on some seiously challenging roles, and outshone everyone else in the films.

I hated the "glittering vampires" series that catapulted her into the limelight (Some things you just can't not see again, no matter how much you try, but I did it for love, took it on the chin, and have been living in denial ever since :->), but she has proven to be an actor with tremendoous range over the years.
