The film’s light-pink and dark-green palette makes it look like Lilly Pulitzer was hired to design Hook. Jon M. Chu has directed it so dutifully that no musical number can become a showstopper, which doesn’t really matter because the film’s audience already knows the songs by heart. Heart, however, is what the film lacks. It contains nothing within a Kansas mile of Judy Garland singing “Over the Rainbow.” There is no longing here, nothing sad. Emotions in The Wizard of Oz were anchored to Dorothy’s dream of a world in which her relatives and the people in her town could be other than what they were. Wicked’s longing is to be a Harry Potter movie.
