I don't think there are many Korra viewers on avs. I could be wrong of course, but whenever I mention it no one really seems to care.
I thought those episodes were fantastic. From the animation (I'm really glad this series made the jump to HD) to the acting to the score to the back-story, there wasn't much not to like.
For anyone out there who hasn't seen Korra/The Last Airbender, I'd highly recommend them both. Don't let the fact that it's on Nick scare you away. They're both great, though they both take a few episodes to find their groove. While not really directly comparable (though some elements may be), I think that if you're a fan of Miyazaki's films you'd like these two series. The depth of the world and characters along with the questions of morality are similar.
But whatever you do, don't judge the show based on Shyamalan's horrible, horrible movie.
