The Great Gatsby" settles into a traditional groove: scene, scene, montage, scene, burst of violence, moment of reflection. The movie wants to be a "kaleidoscopic carnival," to quote a phrase from the book's description of a Jay Gatsby party, but Luhrmann's instincts seem more traditional, even square, and the two impulses cancel each out. Once you've spent time with his cast, you understand why he was torn.
