The humor is more up to par with The Last Airbender
Varrick is a great character
Mako and Bolin are starting to be fleshed out, they're starting to seem less generic.
- The animation is being done by a different studio and while it looks nice, it doesn't have that "wow" factor the first season had. (Also Beifong doesn't look quite right.)
- The story is really all over the place. Not entirely a bad thing, but there's just a lot going on. Every episode entertains but the season has yet to gain momentum.
Now for the real reason I started this topic.
The above preview is for the next Korra episode. The animation is being done by Studio Mir (who did season 1). You can tell its way better. (The clip is pretty much spoiler free if you've saw last week's episode.)
