Wow. That was the best movie I've seen in a long, long time. It shared aspects of Akira and the first Matrix movie, and was as much like Final Fantasy as Spirits Within wasn't. It was so good. The full cast of characters were there, the locales were there, and updated version of key musical themes were there. The remade theme for Sephiroth was especially effective given the context of the scene.
Though I pirated this through a co-worker/friend, I don't feel a single iota of remorse. This was too good to wait for. Sadly, I've not been able to locate the soundtrack - which doesn't even come out in Japan until the 28th of the month. Sigh. I need that Sephiroth mix.
Update: ...one thing I meant to point out was how stylistically unique this film is. This is a perfect example of what CG-animated films should be like. I can only hope that this is the beginning of a trend.
