Honestly I tried rewatching Korra recently cause my partner had never watched Avatar so we were watching the whole thing. We couldn't make it through Korra, it was just painful. The Korra's dynamic with pretty much all the villains were fucking shit. The Equalists and Zaheer easily being the worst. Zaheer was the worst in my opinion. The Equalists felt entirely unresolved, and Zaheer just felt like an inconsistent strawman. It sucks cause the Equalists in particular were an interesting villain with a lot of potential, but they just dismissed it all by being like "oh the leader is a liar, so I guess we can just ignore the valid concerns and problems that birthed the movement in the first place."
I'm hoping the new show does better.
