I highly recommend this animated series. It is visually stunning with gorgeous lush backgrounds and excellent character animation. The way the characters move so fluidly through their different "bending" actions based on different martial arts styles is amazingly realized.

Best of all this show has terrific characters and a kick ass story that continues to develop from episode to episode. Aang is such a wonderful character, whose sweetness and innocence contrasts so well with the ruthless and cynical characters he comes into contact with. Prince Zuko is also a really fascinating character because he isn't just straight up bad, he is drawn with many shades of grey and is a very sympathetic "villian." (I hope he joins Aang and his friends' side in the end!) If you want a show with great great story-telling, interesting characters and beautiful animation this is it folks!
