I watched it on my cable box this morning. In-demand is such a cool idea.

It was a good story, although it did move a bit quickly. There was almost no build up, and made a very steep climax. I myself enjoy movies that have a very long buildup, because the pay off at the end just seems that much more spectacular. But, it's the Final Fantasy style I realize, and it was still an enjoyable movie non the less.
The graphics and directing were... spectacular. That's all I can really say. The animation, the detail and the attention to shading and symbolism was just fantastic. The whole time, I could easily forget I was watching something generated by a computer. It all went down like cherry wine.

The fight scenes, what can I say about them? Perfect as always, once you look past the physical limitations each player seems to break every five seconds. A physics professor would tear his hair out in frustration watching those fight scenes. But, it's an action movie. A japanese one at that. Even bruce lee screwed his physics up when you take a careful look, so all is forgiven. The giant leap Cloud takes about 3/4ths of the way in the movie to destroy Bahamut Sin was still pretty cool, despite the imagination needed to make all that happen. Final word: Don't go back to school in August telling your teacher that flight would all be possible if we all just jumped off steel girders and relayed someone up like acrobats.
The weapons were well designed too. There were lots of cool weapons in the movie that were focused on much more accurately than the game depicted. Kudos to the designers of Barret's gun.
American wise, the voices were good. Cheesy, yes. Over played, yes. Something I would expect from a highschool drama production, absolutely. Emotionally moving? Yeah, pretty much. It wasn't too bad. It just left a soapy aftertaste, that's all. That's a bane of all dramatic japanese production though, at least in my opinion. (Please don't send me mail on this

)
The music as Drey pointed out was also very fitting. It made my nipples harden like saphires.

That's all. Watch the movie. It's good.
