I have just finished a rewatch of avatar (this is my first watch since the initial airing on TV), and I fell more in love with the show. Now, I have moved on the legend of Korra which I have never seen, and I am trying to figure out what type of show this is. I understand that they scaled it down (I'm only on episode 8 of the first season) to focus more on everyday life in the world, but I find it very strange that these episodes are feeling like a cross between WWE and SVU. It is really throwing me. One thing that is shocking me is how close the situation of Republic city is to our current predicament in the U.S. and how Tarrlock (in EP. 8) is basically Trump so far. I am liking the show, but I am trying to figure out how the show ended up like this and does it ever expand to see the progress in the rest of the world? Please no spoilers.
Yes, further seasons explore parts of the world outside Republic City. Also, if the animation quality in season 2 doesn't look quite up to snuff, that's because a different animation studio (Studio Pierrot) handled most of that season. 3 & 4 are entirely Studio Mir (They did season 1).
