One of the best animated shows I have ever seen. Avatar: The Last Airbender features a world where some people have powers to bend the elements, such as fire, water, earth, and air. The story focuses around Aang, a 12 year old Airbender who is the Avatar, a person who can master all 4 of the elements and has the duty of keeping balance in the world, and his friends, Katara, a young waterbender, Sokka, a Water tribe warrior, older brother of Katara. and Appa, Aang's flying bison. They are stalked around the world by Zuko, an exiled prince of the Fire nation, as he tries to reclaim his honour, and his uncle, Iroh, a kind, gentlehearted old man. For a Nick show, the language is pretty strong, and death and killing is talked about. There is very mild sexual content, a few innuendos that most kids would not understand, and the occasional kiss. This is a must see. I'm 18 and I still love this show.
