I saw it last night. Someone linked me to it on tumblr. (If you go through the Legend of Korra tag, you'll eventually find a working link)
It was AMAZING. And holy Jesus, I cried so much. Mostly during all the Katara scenes. And how she was talking about how Sokka and all her friends are dead.

Oh god, having Katara as a part of this series is going to do horrible things to my emotions. I started sobbing every time she came on screen.
Anyways, I LOVE Korra. I think she's a total bad ass. I love Tenzin too. I love everyone

It's all so perfect.
The original series is obviously better. But this one isn't bad at all. But oh my god, I wanted to KILL Tenzin's daughter when she interrupted Katara about to freaking tell us what happened to Zuko's mom. D:<
Anyways. Yes. I really enjoyed it, despite all my crying. haha. I suppose I'm an emotional mess when it comes to fictional characters I'd grown to care so much for.
