Supposedly each book shows how Aang masters each element, so WTF is wrong with this, during this season 2 we have only seen one episode where Aang actually is learning earthbending, and that was enough to almost master it!!!
Just one day, to learn the complicated arts of bending the element of earth!!! it took YEARS for other avatars to learn and master one element, but aang can do it on one day!!! That's wrong. I know that he has little time before the comet arrives, but why doesn't the season concentrate more on aang learning earth?? At the end of "bitter Work" he could move a rock, and now he can make stone walls like he has been earth bending all his life!!
For book 1 it was the same only one episode of aang actually learning to bend it!
DON'T YOU GUYS THING THAT BENDING LEARNING SHOULD BE SLOWER?? AND THAT EPISODES SHOULD CONCENTRATE A LITTLE MORE ON AANG ACTUALLY LEARINIG TO BEND??
