Yeah, so I totally get why some don't like Korra as a character. I think the writers made a lot of missteps in this show, and made some pretty poor decisions with how they presented this character. There is nothing wrong with flaws, and struggles, and I think all the plot makes sense. But it's how they chose to present it, that I think really turned off people from her. But after the second half of Season 2, and all of Book 3....I don't get the hate for her. And in terms of her being a "shit" avatar, she's technically done more than any previous Avatar has done in a long time. I just think, in order to make the show seem competitive, they've had to make Korra come down to the level of people that probably shouldn't be on her level. They've made her stumble and be a weak fighter, for the sake of making it a more even leveled conflict vs. and out and out domination of the Avatar.
And to be fair, I think this was a problem they were always going to face. They never had this issue with Aang, since his big battle with the bad guy was always off in the distance. And it was the adventure format where each little side thing, didn't need to be a situation where he had to get bested for it to be a conflict. But now that this show is more centered on a single season conflict and the main protagonist having to clash with that conflict throughout, they've defaulted to a simple narrative structure that requires the protagonist to get bested early on before coming back and winning. Problem is, how do you do that with the Avatar? Well, they've made Korra weak as a fighter (in this case, it was the metal still in her body, and everything else weighing down on her. At least there is an explanation for it).
It wasn't even like the Avatar state move that was used, was anything special. Plus, while Kuvira was besting Korra prior to her going into Avatar state...she wasn't exactly destroying her either like she should have (given Korra was really bending very poorly). I still think this fight was kind of poorly handled. It ended up making Kuvira look really weak.
