THIS SHOW IS GREAT! DISCLAIMER this has spoilers!
My all time favorite tv show highly recommend to anyone who wants a good adventure this beat the hardest thing to do in shows and that is to make have a little bit of dialogue and a little bit of action in the scene when Iroh tells Zuko that he treats him like his son they then put in further information to that by him nagging like a parent. I watched the show like 10 times and kept on coming back because there is soo much detail that you won't notice. Zuko's character development is on point same with every character. you can see this from season one when Aang is a goofy kid and then in season two he takes responsibility for ba sing se falling. When Zuko attacks the southern water tribe and Aang sees the villagers in pain he stops and sets the terms fully confident he can escape.
