Roger Ebert from Suntimes: "Prince of Persia: The Sands of Time” is a children's story beefed up to appeal to young teens. It's based on a video game, but don't make me play it, let me guess: The push-button magic dagger is used in the game to let you rewind and try something again, right? Since anything in the story (any death, for example) can be reversed, the stakes are several degrees below urgent.
