So far, so B-movie, but the film kicks up a notch after the stolen robot, Chappie, is animated by Dev's AI program, rapidly develops from childhood through strutting rap gangster adolescence to adulthood, and tries to reconcile the opposing moral frameworks of his gangster parents and his creator. Yolandi and Ninja play Chappie's surrogate parents with broad but credible strokes; Hugh Jackman is a somewhat cartoonish embittered alpha male who plots to supplant Dev's robots with his own creation; Sigourney Weaver doesn't have enough to do as their boss. The story's mix of broad comedy, pathos and noisy violence is pretty uneven, doesn't always make sense (Yo-Landi and Ninja let Dev go after he's animated Chappie, even though he knows where they live), and reverts to B-movie cliche in the final showdown, a version of the three-way stand-off in The Good, the Bad and the Ugly, but with much bigger guns. But Blomkamp's direction is fluidly kinetic, there are some clever twists, and Chappie is a terrific CGI creation. He may lack a recognisable face, but the voicing and motion capture work of Blomkamp regular Sharlto Copley, and a script that nicely charts his intellectual and emotional development, create a wonderfully engaging and sympathetic character who is the human heart of this patchwork fable.
