The folks at Pixar can do no wrong with Monsters, Inc., the studio's fourth feature film, which stretches the computer animation format in terms of both technical complexity and emotional impact. The giant, blue-furred James P. "Sulley" Sullivan (wonderfully voiced by John Goodman) is a scare-monster extraordinaire in the hidden world of Monstropolis, where the scaring of kids is an imperative in order to keep the entire city running. Beyond the competition to be the best at the business, Sullivan and his assistant, the one-eyed Mike Wazowski (Billy Crystal), discover what happens when the real world interacts with theirs in the form of a 2-year-old baby girl dubbed "Boo," who accidentally sneaks into the monster world with Sulley one night. Director Pete Doctor and codirectors David Silverman and Lee Unkrich follow the Pixar (Toy Story) blueprint with an imaginative scenario, fun characters, and ace comic timing. By the last heart-tugging shot, kids may never look at monsters the same, nor artists at what computer animation can do in the hands of magicians. --Doug Thomas
