The movie looks totally amazing, and much much better than the anime (so don't avoid the trailer if you look at the anime link first and don't like it). The trailer is in Japanese (with no subtitles), but that didn't stop me from enjoying it.
I wish I could make screenshots from it, there are so many great scenes in it! And man, Japanese people are soooo sexy. Mmmmm.
The song in the second half of the trailer is great, too. I'd love to know what it is.
