It's kind of a strange movie to describe. With Tim Burton as one of the producers, that's probably to be expected. All CG animation and quite well done. It takes place in a post-apocalyptic world where nobody is left except these tiny little doll-machines and one big giant bad guy machine. Not quite sure how they work or what makes them go, but it's not really all that important. The combination of tech and spirit in the story line made me think of Final Fantasy: The Spirits Within and a few other only vaguely remembered movies.
It's not a long movie at just over an hour and is pretty easy to watch. I quite enjoyed it.
4 stars out of 5.
