Thanks for everyone who directed me towards the leak. My girlfriend had lost her 3DS and was so down, so I surprised her with this. She's a major Avatar Fan just like me, and it really helped cheer her up.
I allready know I'll be going to buy the DVD or Bluray collection for this so, I don't even feel guilty about watching this leak.
The writers and the whole team behind this have my utmost respect. This is how you do a great TV show. This is how animation can enhance storytelling and create unique and timeless worlds and fiction. The quality of the animation, composition and special effects detail is outstanding. It stands up there with the best of TV animation and even makes some animated movies look extremely cheap.
I am extremely impressed that they managed to marry the more adult tone with the whimsical comedic stuff of the original series. There is just enough nostalgic nods in there for fans, but the series really stands on it's own two feet, and Korra seems to be one of the strongest lead characters I've seen in years. A young women who isn't a sexed up bimbo or any other kind of male stereotypical depiction of strong women.
