The Snow White story is retold as a slightly goofy comedy in Mirror Mirror. The intention to reshape the legendary fairy tale is good, but Mirror Mirror winds up feeling half-baked, perhaps because of the script, and perhaps because of the occasionally drifting direction from Tarsem Singh. They cast it like they knew what they were doing—Julia Roberts as the evil queen, handsome Armie Hammer as the dashing prince, seven terrific dwarves, and an unmistakable find in Lily Collins as Snow White—but the film never knows what tone it should set. It’s not a complete embarrassment, but that may actually be worse: You can see the potential this film has—and squanders—as a fractured fairy tale.
