I heart ATLA and Korra. So, so, so good.
Totally!!!! I love all most of the characters, Aang, Karara, Sokka, Toph ( god bless this girl!!!!
), Zuko ( emo but soooooooo much better then emosuke), Azula ( I love this girl, she's a kitten but she has her moments that I find really great and idk, I feel her pain so much at the end), Iroh ( the Chuck Norris of Avartar in my book, he's so awesome and his relationship with Zuko is so awwwww!!!!!) etc.
I even bought all the books, I can't wait to read the new one that is supposed to be out by now 
Overall, Avatar is my new kitten....oh and Korra also is so great, funny as hell with Tenzin and his family, Bolin, Asami ( love this girl!!!) oh and seeing Toph again...daaaaaaa that feel!!!!!!!!
