Plenty of animated family films feature chaos, but few are, in and of themselves, chaotic. Well, Happy Feet Two is a cartoon in a blender. The central story amounts to not much more than a tribe of penguins trapped in a hole, and the tangents are bizarre and totally pointless. There’s a puffin (the voice of Hank Azaria) who journeys to the South Pole and masquerades as a penguin who can fly, because that’s what we needed in a sequel. There are two krill (Brad Pitt and Matt Damon) who break away from their swarm in the interest of existential philosophy … or something. And there is the continued misconception that Robin Williams is funny. Happy Feet Two delivers very few laughs, some odd song choices—including a baby penguin aria—and the obligatory global-warming warning. Now you’ve been warned about the rest of it.
