My favorite scenes:

The beginning, with the blitzball game, and Auron walking around like everything is fine, while everything is pretty much being destroyed by Sin. The background music is awesome, too.

The wedding is brilliant, as well. I loved it. They're professional wedding crashers.

The spring. It's just so touching and everything. But the only thing I don't like is that Kimahri watched the whole thing. Sort of ruined the mood.

The ending was very deep and sad, but just what I wanted to see.
