I'm not liking it nearly as much as the original. The only characters I really care about, are the ones related to former characters. People like Bolyn, Mako and others seem rather flat right now and I could care less about them. The show doesn't seem to have the "brevity" that the original did. Rather than it feeling like the bad guy is changing the world, it instead feels like he's only changing a city.
That being said, Korra, Lin and Tenzin are godlike.
