I'm so sorry for that boy and his aunt. Of course you can keep playing Avatar; you're the real heroes!

While I can understand the argument that the boy playing Aang looks like Aang from the original series, Katara is so obviously dark-skinned, the actor cast to play her is so obviously pale skinned. There is no logic.
