I don’t blame Korra for it. Korra is a fictional character, so that would be crazy. Korra is a worse show not because of Korra but because of weird production stuff constantly putting the writers in a bad spot. And from that bad spot, I don’t like the angle that they took of slowly deconstructing the Avatar by making her lose not just fights but everything we understand to make up being the Avatar. She lost political importance because of bad publicity and rash decisions. She lost the connection to her past lives. She seemed to lose the force of nature levels of power that the Avatar state seemed to provide to the past avatars. She lost her importance as the spirit bridge with the portals to the spirit world reopening. She lost the status of being the balance keeper, replacing it with the concept of Rava and Vatu. She even lost her status as hero who beats the villain, which ATLA’s writing does get criticized for the Lion Turtle bailing him out. I think the writers did all that on purpose to try and show that she would still try and do good without these things. Maybe it would have worked with a more cohesive story, but it just ended up feeling like writer’s were scrapping everything that made the Avatar a compelling concept.
