This is a CG-animated fable about some animated dolls surviving after the destruction of humanity. Humanity was destroyed by an invention of a brilliant scientist, an artificial brain that was seized by a patently fascist government and employed in war. Stuff happens. It is a spectacle to watch, the premise is tired, I could not discern a coherent theme. Something about souls.
The underlying theme I got from it was that something spawned from pure intellect is easily corrupted and ultimately destroys humanity, while that which is spawned from even fragments of a mystical creation - the soul - is ultimately pure, good, and will save the world.
Overall it seemed mostly like a bad storyline overlaid onto a lot of explosion and weird living burlap bags.
I thought it was pretty. Not much more to be said about it, especially with the laughable dialogue.
