"9" is a really really good film. Its ending is a bit weak, the mechanics of it should have been a little different, to make sense, as far as I'm concerned, but it's well worth watching despite that. The animation is superb, especially in the characterisation and movement of the little hybrid doll-like humanoids. 95% of the film is a joy to watch, your heart will be totally captured by the characters.
The child actor in "Where the wild things are" was utterly superb. His character of Max was as real as real can be. The scriptwriter and director obviously had fun fleshing out the story and turning it into a parable examination of this young boy's emotions, motivations, aspects, and relationships with family members. The people I saw it with said they wouldn't take young kids to see the movie, it would be too scary.
Going to see Avatar asap.
