I've never really officially been a fan of the show, but I have watched all of the episodes out of order because I always turned nicktoons network on hoping for a chance that they would be airing one of the classics (Ren and Stimpy R.I.P.). This animation was pretty great, and from what I could see/hear all characters were represented almost exactly as they would be, and it was funny. And as I assumed, nobody likes Korra. (Even I could see that after a few loose episodes.)
Funny thing, I was getting pissed off at nicktoons for killing everything else besides Dragon Ball (DEFINITELY not a fan, not my thing..) and Avatar. But, Avatar: The Last Airbender I found to be kind of entertaining.
