Just started watching this show after several years of seeing bits and pieces while my brother watched it. I'm about 6 episodes in and it's pretty good. Sokka is funny, Katara plays the caring sister well, and Aang is still a mystery. Why didn't he want to be the Avatar? How does he control his bursts into "Avatar mode"?
I like how we get to see developments within the Fire Nation, but still a lot of questions there too. Why did they attack to begin with? What's their endgame, besides simple domination?
I'm not asking these questions to be answered, as I hope they will be as I continue watching the show.
