Greatest Animation I've Seen

Greatest Animation I've Seen
Ok This is hard because I'm a huge fan of Pixar and everything they've ever done however the best piece of animation I have ever seen has to be the epic Final Fantasy 7: Advent Children, the movie sequel to the best selling playstation game.

This is for two reasons; 1. I am a huge Final Fantasy fan and even though FF8 is my favourite I've always had a special place in my heart for FF7, basically this film is purely for the fans satisfaction it answers none of the questions you may have with the story from the game, its a standalone story that to be honest is very heavy going and hard to understand.
So what makes this so great?

The animation is superb, from the second you see it your literally blown away, no 3D animation I have ever seen looks so realistic, pixar may be the kings of 3D animation but they always use a very cartoon like style that is great for their target audience, however Square Enix use realistic looking characters. The same amount of care has been put into this game as Square Enix put into any of their games, it looks superb and sounds great, the music in particular is epic in everyway. But what makes this film truly great is the way they use animation, because the characters look so realistic it is possible to wonder why not just make a live action film? It's in the fight scenes that the reasons behind the animation truly shows.

Everything is so over the top characters jump miles (literally) into the air swinging huge weapons with all the grace of a ballet dancer. It's hard to explain but take for instance 'Flying Tiger Hidden Dragon', although a great film you always notice the fact that the charcters are on wires, however Advent Children through the use of animation makes you believe that the charcters are capable of such gravity defying acts.

What makes this film a great piece of animation is not only that it has amazingly detailed characters and enviroments but also that it uses this animation to do things that wouldn't be possible in any live action film. Anyway I can talk forever about Final Fantasy so I think It'd just be better to watch a clip.
