Except... no. It's really not just "arguing over the trim colours". It's an important part of this if you're creating what amounts to a fix fic for the entirety of Korra's personal history - which, by giving her achievements she could genuinely be proud of, is exactly what you're doing - because for a fix fic to work, you have to know what bits to fix in the first place.

Something that stuck with me when I read Harry Potter and the Methods of Rationality was a line from chapter 7 that said "If you can't criticise, you can't optimise". Just saying "that's just poor writing" is so vague as to be meaningless; you have to actually break down the elements of the show and go over what does and doesn't work with a fine-toothed comb before going through with it. You've got your reasons for hating the shit Korra goes through, fine, I get that, fill your boots. She's been shat on from a great height, partly by
fate and partly by the writers not giving her the same chances that they gave Aang (so, er, entirely by the writers). This is not in dispute. What is, is that that's the only thing wrong, or indeed the only thing with good/interesting elements.

Look, I haven't watched much of the show. I am not as familiar with it as you are. I am, however, familiar with criticism; "that's just poor writing" ain't fuckin' it. It's bad because it sucks, it sucks because it's bad. Hurrah. You don't want realpolitik in your cartoons? Well, hard cheese for you, because you've got it anyway. Look at, for example, the ways Raiko abuses his position, look past the fact that Korra was winning an argument (and at the fact that the Avatar and the leader of Republic City were squabbling like toddlers over the last sweetie in front of the assembled press do you seriously not get why Lin had to step in), look at that and think about how you can make it better. I'd really like to see what you would do to make Raiko work as a good guy in UF. I want to see you convert the startling array of idiots on Korra's side into people who deserve to be on her side. I know you could do it - hell, making the White Lotus into not-morons was proof enough of that - but it's a question of whether or not it's worth the effort.

The answer, for those playing along at home, is yes.

That's what fix fics are supposed to do.

Of course, you'll almost certainly ignore this because it doesn't fit into your preconceived narrative that the good guys have to win because they're the good guys and the villains aren't allowed the remotest semblance of a good idea because villains r bad, but w/e, piece said, I'm out.
