I can accept a "family" film that bucks formula and isn't cute, as this film certainly isn't. But, there is an odd, sad, maybe even hopeless tone to this film, and once our hero arrives 'where the wild things are' I personally couldn't wait for him, nor me, to get the heck out. It wasn't intended to be funny, it was intended to explore the mind of a disturbed child, and that's the level where it succeeds -- it's disturbing. To be fair, most of my party, including 10-11 year olds, enjoyed it, though none thought it was "great".
This looks like an early rough cut of a Pixar film, though Pixar would never put into production a script this weak. Even at only 70 minutes the premise of the kid's book is stretched thin. The jokes and gags are only so so and the character animation is not very imaginative. Our theater did not show 3D even though this is how it was advertised! 3D would have made it better I'm sure. Not good, but better.
The humor in this film is stale and the jokes will be new to only very young ears, who should enjoy thist well enough. Adults will probably be bored as even the eye-popping 3D doesn't make up for tepid, predictable action sequences and performances that often seem often phoned in. Dull for all but ages 2-7.
