Superb Japanese animation from Hayao Miyazaki. This is the film he did before "Spirited Away" and shares much of the same style as that film. It's a wonderful cinematic creation from a fertile imagination exploring the man vs nature theme. One warming though. Yes it's animation but it's not a children's film. Lots of violence, blood and graphic war scenes. That said, I let my kids watch and they really enjoyed it. Like most animation, it can be a bit jerky and the lip-synch poor. It doesn't look like any computer animation was used. I found the ending satisfying but a bit ambiguous.
If you like Japanese animation, you shouldn't miss this. I'm looking forwarding to digging up Miyazaki's earlier works.
