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.

One of the most endearing animation films created
16 January 2005 | by (United States) – See all my reviews

Pixar is the best! Of them all, Monsters, Inc. takes the cake. The realism of the characters' movements & feelings is perfect. The ending is a tear jerker on a happy note. At first I was concerned with the plot of monsters scaring children with a "business as usual" attitude, but right away you discover that the monsters are as terrified of the kids as the kids are of monsters.... wonderful juxtaposition throughout the film... a totally enjoyable, feel-good story. Buy it for the kids and let them watch it over and over. (adults may want to sit-in on more than one occasion themselves). Personal Note: For me, a mystery about this film was "Roz"; the voice reminded me so strongly of the grandmother in "Dinosaurs", and I thought the character drawing was similar as well; upon researching the two, I found they are definitely different actors.
