Loved it. People expect that it will be like ATLA (another favorite), but the point of the story was to expand the universe while giving a fresh take of the avatar. If Korra had been exactly the same, the story would not have been as interesting. Amazing villains and animation- the pacing can get rough, but it's understandable considering how much Nickelodeon screwed around with the show's renewal. I love how it's definitely a darker take, it opens up a lot more to the viewer.
