(I’m going to spoil part of S4E6 here. It’s important, but I’m willing to bet most of you saw it coming a mile away.)
Okay, so anyone seriously content with the quality of the fight scenes from Korra, I welcome you to watch any of the significant fights from TLA. In particular, ones involving Firebenders. The cave fight from the end of season 2. Azula vs. Team Avatar in “The Chase”. Azula vs. Zuko in “The Phoenix King”. Virtually everything in “The Blue Spirit”. The fight at the end of “The Waterbending Master”. The list goes on and on. They’re visually interesting and functionally compelling. It feels like a real fight, involving the power of the elements, and even the ones that feel one-sided act like, yanno, real fights.
Now look at some of the fights in Korra. Even at its worst, I cannot name a fight scene in TLA that was quite as dull as Korra vs. Kuvira. That fight would have been dull even if it wasn’t the same as virtually every other fight in the show. It was obviously and stupidly one-sided. This at least made a little sense with Amon; Amon was supposed to be this unstoppable badass nobody understood, and they offered a reason for why they kept missing, his bloodbending. But even then it was horribly dull. Even with the justification that Korra’s not on her A-game, there’s no reason for her attacks to be so ineffectual. There’s a fundamental difference between “I can avoid your attacks” and “I can avoid your attacks by emulating Little Mac”.
In TLA, most powerful bender attacks were treated as though they were powerful. You either countered it with your own bending, you blocked it and it was gonna hurt, or you got out of the way, and not just by ducking and weaving. It made the fights feel real. It made them feel powerful and meaningful. It made it feel like the people involved were tapping into the elements themselves, rather than throwing glorified Hadokens.
And beyond that, there’s the aspect of balance. In TLA, there was very rarely a case where a fight was completely one-sided. Even the fights between enemies with an obvious skill gap - fights like Katara vs. Master Paku - there’s still an actual fight there. The only times you see fights go truly one-sided is when the point of the fight is to completely humiliate the victim, and this is used sparingly enough that it’s actually meaningful (for example, Toph vs. The Boulder - that’s not a fight scene, that’s a “this is how OP Toph is” scene). And more often than not, this is subverted - see also: Aang vs. Admiral Zhao in “The Firebending Master”.
In Korra, that’s almost every fight. There’s little drama - the winner is clear right from the start. Korra doesn’t land a single hit on Kuvera, and Kuvera spends the entire fight toying with her. That would make sense if Korra was some greenhorn bender with no experience, but she’s a fully-grown avatar who has been bending and training since she was a toddler. Somehow, this doesn’t add up to “anywhere near as good as Zuko, Katara, or Aang were in season 1”, let alone Toph in season 2. The fight becomes a farce; completely unbelievable even given the circumstances, and the way they do it treat Korra’s bending not as the mighty power of the elements, but rather like a person throwing rocks who happens to have a zippo lighter and a super soaker. It’s pathetic and disappointing, until she goes into the avatar state… Which lasts all of about 10 seconds before the plot kicks in. Yes, it makes sense to show some contrast there. It makes sense to build up Kuvera as a badass and show that she’s a talented, dangerous bender. But this does nothing of the sort. Kuvera is just your standard metalbender; it’s just that Korra sucks. It’s just really disappointing. These are the high points of tension in the show, and they’re just completely flubbing them almost every time by making the fight a foregone conclusion, and never throwing any curveballs. It’s awful. And it bugs the crap out of me.
