I can not sing the praises of this show enough. From the first time I watched it in the seventh grade, to the last time I re-watched it last year, the show looses nothing over time. The characters are very well developed. Aang' internal struggle between his peaceful nature and his constant need to use violence to solve problems around him. Katara's motherly instincts and underlying hatred fort he people who took her mother away from her. Toph's tough exterior contrasts with her sensitive, thought deeply buried, inner self. And then there's Zuko. I don't think I've ever known a character in fantasy that could exist so easily in the real world. The mirroring themes between Aang and Zuko's life were an incredible story telling method seldom seen in television shows geared towards a younger audience. And then there's the animation. Not only does the concept of bending ignite the imagination like nothing else, but the animation is some of the most beautiful I've ever seen.
