This film features wonderful animation and an unusual story. There's an unexpected surprising twist ending but the anti-technology pro-ecology theme gets pretty tiresome when repeated throughout a film--if they had left it to the end, it would have been better. A bit more action and human interaction between characters would have been an improvement as well. Still it was a nice attempt at telling a Science Fiction story that raises serious questions about how man treats his environment.
