How do you provide a challenge for Thor, one of Marvel's mightiest beings? In the first movie, they took away his powers. In Thor: The Dark World there's an ancient threat that could destroy Earth, Asgard, and just about everything else. There's almost the entire cast of the first movie, plus a little too much humor.
Thor: The Dark World may skimp on character development (and use Loki's illusions a few too many times), but it's pretty exciting and entertaining.
Overall grade: B-
