The Mummy: Tomb of the Dragon Emperor is thrilling, mindless brain candy. Not that there's anything wrong with that, but if you're cutting down on going to the movies because money's tight, you might want to spend your money on "The Dark Knight" instead. Lots of action, and Jet Li's a high point of the movie (plus there's yetis!). But Maria Bello and her awful British accent were a real distraction. Couldn't she have played Brendan Frasier's American sister instead of taking over Rachel Weisz's Evie character?
