I totally agree! You can still fit heartwarming moments in between badass fight scenes with magical kung fu, right? ;)

(But seriously, like Toph pointed out in that one episode - Zuko could have/should have turned out a lot worse than he did. I blame Iroh for the fact that Zuko isn't Crazuko. He kept his nephew grounded with kind words, encouragement and tea. And occasionally music nights and aborted attempts at teaching him Pai Sho.)
