You can forgive an adventure movie just about anything except dullness, which is all this video-game adaptation has to offer thanks to a labyrinthine plot. Angelina Jolie plays the title heroine, a comely British explorer who uses a push-up bra for a compass, and she certainly cuts a striking figure. But with unimaginative action scenes and lame special effects as the only other diversions, even her pouting and posing become boring before long.
