In the latest 3-D CGI extravaganza, Megamind (voiced by Will Ferrell) and Metro Man (Brad Pitt) take sides on Earth after fleeing their own planets: Metro Man plays the hero, Megamind the villain. After tearing through Metro City during another one of their battles, Megamind finally wins. But his celebration doesn’t last long. With no one to fight, Megamind grows bored and decides to shape a TV cameraman (Jonah Hill) into a new nemesis, who has no interest in playing the good guy. Megamind is faced with a crisis: Does he join forces with his evil creation? Or does he switch sides and become a superhero who saves the day? You probably already know the answer. Like the funny and smart Cloudy With a Chance of Meatballs, Megamind keeps its story centered without cramming in too many throwaway scenes or juvenile jokes. Ferrell injects it with his usual mix of clueless confidence and undeserved arrogance. Still, Megamind can’t resist playing by the rules much of the time. There’s nothing groundbreaking here, and even the movie’s best scenes are cribbed from other CGI hits. Megamind’s greatest strength is corralling all of them into a movie that isn’t all that super, but it is an occasionally funny good time.
