I'm enjoying it. Politics done right is always fun to watch. Funny enough, it actually reminds me a bit of Season 1. Wu is, by all rights, the heir or King or whatever you call it, but he's also unfit to rule. Kuvira, on the other hand, has actively been working to unite a broken nation, even if she's rather abrasive about it. She's going to highlight Wu's inability to lead, and as usual its going to work to her advantage, just like it did when the Equalists called out the Republic City council.
Also, S4 is poised to strain a lot of relationships. Mako and Bolin will obviously clash at some point, as Mako is Wu's bodyguard and Bolin is Kuvira's... lieutenant? Bolin's unlikely to abandon Kuvira unless she outs herself as evil. He's already stood against Opal and they're together, so I doubt he'd drop her for Mako either. And let's not forget, the Earth Kingdom has a history of being incredibly shady, and Wu is an entitled rich kid. From there, its easy to slip into doing something deplorable. The Air Nation (did anyone else notice Opal said Nation, not Nomads?) is spread thin despite their peacekeeper role, and they're going to have to fail big time in order to get the titular hero to assume her destined role. I'm thinking Tenzin is going to die, or something along those lines. Asami will hopefully have to pick sides, because she's still a badass as far as I'm concerned, I always like seeing her in action and she's the only nonbender of any significance, other than Varrick. Korra is probably going to be insufferable once they find her, which I both am and am not looking forward to.
Eh, realpolitik is fun. There's a reason why people say not to talk politics with your friends. Can't wait to see how the Avatar crew handles it.
