Beautifully animated, with excellent character design and development

Rating: 10/10 (9 December 2014)

This is an animated feature produced by Pixar. There will be spoilers ahead:
There's a great deal to like about this film. The animation is wonderful, the characters are well designed and the characters mainly have strong, well developed personalities, particularly the two leads. The voice work of John Goodman and Billy Crystal as Sully and Mike is perfectly meshed, the two working together to make their characters come alive.
The premise is that monsters are simply doing their job when they scare children (monsters in the closet, under the bed and so on) and the power which runs their city comes from screams. Sully is the champ and he and Mike are a team. The chief villain, more or less, is another monster and Sully's main rival, Randall, a chameleon voiced perfectly by Steve Buscemi. There's an interesting, probably unintentional, resonance back to another film and role for Buscemi in what happens to doors to children's rooms when the children are no longer sufficiently frightened by monsters. But I'm weird, so I would make the tenuous connection.
The monsters are actually more terrified of children than children are of them and most of the movie turns on this, with a small girl named Boo (naturally) coming through her door into the monster's city. Much of the film is concerned with Sully and Mike trying to return Boo to her room.
The action is fast and furious, the plot is well crafted and executed and it's a fun ride. The ending is perfect.
This film is available on DVD/Blu-Ray and is well worth watching. Most highly recommended.
