Does anyone remember watching this show? It was on only a few years ago on Nick but damn, wasn't it a fine tv show. Who would have thought a cartoon on nick would 1. be serialized and 2. only last 3 seasons. The show had a great mix of characters, action, drama, humor and music. I remember that arch where aang lost appa, so tragic!
Apparently there is a new show in the works. Legend of Korra, she is the next avatar after aang, she is part of the water tribe and wil be learning the elements from aang/kotara's son, while it might be hard to topple an asteroid coming to earth, the premise mainly is about the rivalry between two factions of groups of anti/pro bending. It is coming out in 2012 and they released some concept art.
