After the frenetic tedium of The Secret Life of Pets, French animation studio Illumination Entertainment returns to heartwarming form with this comedy about a group of anthropomorphized music-mad critters. Matthew McConaughey heads a worthy cast as the voice of a koala bear who stages a singing contest in a last-ditch effort to avoid foreclosure on his theater. The CGI pops with alluring color, and the screenplay offers a few big belly laughs and some amusing Rube Goldberg-esque sight gags. The plot may be shopworn, with not much aimed at adults, but the film's message that collaboration can reap greater rewards than competition is appropriate for all ages. With the voices of Reese Witherspoon, Seth MacFarlane, Scarlett Johannson, John C. Reilly, Jennifer Hudson and writer-director Garth Jennings (Son of Rambow), who saves the funniest role—an accident-prone, glass-eyed iguana—for himself.
