I was one of those lucky enough to watch this show at a relatively young age, 11 I think- coincidentally the same age as Aang in the show. Because of it I started meditating and understanding Chakra systems and spiritual knowledge at that age! Bless this show for all that it gave me!
FYI- If you haven't watched the show and are curious about its spiritual knowledge, reference season 2 episode 18 "The Guru" the one I am watching now!
I Feel like this Show was Approved to Appease the Criticism that Nik Kills Brain Cells.
Not as awesome as the first Avatar, but still love this world and want to see more of it. There is a comic coming out this june, and if history repeats itself they will make a few more comic books, then kill Korra and incarnate a new Avatar liek they did with Aang (I believe it was four comic books). I hope they bring it back!
