It is excellent.Every character in the story is described really well.I loved it hope the new avatar the legend of korra(a sequel to this series) does really well.This story is about people with different elemental powers divided in different nations(elements such as air,water,fire,earth bend to their will),but the avatar is one who should master all the four elements and bring balance to the world.avatar is also the spiritual leader there as he is only one who is bridge between both material and spirit world.there is Japanese,Indian,Chinese,etc influation.you'll see people with different accents and different bending abilities and thinking too.if you like anime you'll love avatar.
