I got hooked on this show a few days ago, and have since seen the entire series (so far).
I'm not a fan of anime, but I love this show. Ok, it's actually made by Americans, but it's got all the styles of a Japan-made anime. For me, all of the intricate storytelling, the continuity, and the characters make this...dare I say it, even more enjoyable than most live-action shows I've seen around.
Also, even though it's a cartoon, I feel its audience are not necessarily kids. Apparently a lot of adults like it too, and I don't blame them. There are some very wise philosophy and spirituality associated with the series...as well as great humor.
So, anybody else watches it?
EDIT: In the US and want to watch most of the episodes, but don't want to do anything illegal? Never fear! Go here:
