Best "anime" I've seen in a while. Way better than just about anything on Adult Swim or Toonami. Jeez last good anime I saw was Last Exile.
I don't get why people are all feral when you call Avatar an anime. It may not be from Japan, but if you look at the list of artists they are clearly not American. I'm not saying that makes it an anime in itself, but isn't anime just short for animation?
