Heyy now!~ I actually saw.... ONE
episode of this series! and it was pretty
ok! Is it based around Buhddism...? Because of the
idea of avatars, reincarnation, monks, & the
belief of Yin & Yang.

The fighting IS pretty interesting. I was watching the
fight between the water benders. Good moves, its just
that the animation is KIND OF slow, and not so smooth.
But I would definitely watch it again if I knew when.
(I didn't/couldn't check out the clips btw)
