A city of monsters with no humans called Monstropolis centers around the city's power company, Monsters, Inc. The lovable, confident, tough, furry blue behemoth-like giant monster named James P. Sullivan (better known as Sulley) and his wisecracking best friend, short, green cyclops monster Mike Wazowski, 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. And now it's up to Sulley and Mike to send Boo back in her door before anybody finds out, especially two evil villains such as Sulley's main rival as a scarer, chameleon-like Randall (a monster that Boo is very afraid of), who possesses the ability to change the color of his skin, and Mike and Sulley's boss Mr. Waternoose, the chairman and chief executive officer of Monsters, Inc.

Nothing To Criticize Here - Very Solid Animated Film
10 July 2006 | by (United States) – See all my reviews

This is a very entertaining animated film. I've seen it twice and enjoyed even more the second time. Billy Crystal said he enjoyed making this film as much as any film he's ever done, so that's a good testimony that you'll get some laughs and enjoy this movie as an adult, too.

Kids will love it, I am sure. The "monsters" in here are funny-looking and almost lovable, nothing that would scare your kids (or you). Crystal has a bunch of funny lines but overall I found this to be as much if not more of a human interest story than a comedy.

There is a lot of sentimentality to it, even overdone a bit at the end, but that's okay. There is absolutely nothing offensive in here, either. The colors look spectacular, too.
