One of the biggest criticisms hurled at James Cameron's Avatar was that the story wasn't very strong and Sam Worthington wasn't a very good actor. Personally, I'm not a big fan of Sam Worthington; I don't think he gives us enough as an actor, and he was very stale in Avatar. Interestingly enough, though, Worthington almost didn't get the job for Avatar – two other (more prominent) actors were offered the role first.
