Yeah, I'm liking it so far. It's a bit more mature than the original in some ways, which is good considering Korra and friends are older than Aang and friends, but it still has the same charms. I love the characters for the most part, especially the little boy airbender. The art style is similar, but somewhat different, too. Which, again, I like because it matches the setting and the industrialization the world is going through.
I'm ready to start seeing more Avatar stuff, though. The flashbacks of Aang's life were pretty cool, but I want to see more of that. I like the fact that Korra is apparently interacting with past Avatars differently than how Aang did.
It's well-done, and reminiscent of the original series without being more of the same.
