Its an american animation with various hints of of eastern animation or "anime". The two styles blend well and make for a refreshing new kind of animation. The characters both antagonists and pro-antagonists are vivid with each having their own personalitys , experiences and motives. A really awesome touch to the series is the use of real life martial arts moves for the 4 bending styles(water,fire,earth and wind). A good example is firebending which lends moves from real life shaolin style kung fu. The story is well written and takes you on a journey through a new world. If you like a combination of action, humor, drama and eastern culture this is the right serie for you.
