>>106148073This might be just a product of the missed opportunities. Republic City was a cool setting: it reminds me of the Legation Cities in Kaiserreich. Little of the plot really utilized the setting effectively though.
I wanted Season One's whole equalist movement to not just terminate at the end of the season, but continue to be the driving force of the narrative as a political movement. It shouldn't have ended with Amon being outed as a bender or lunatic, but actually been something of a more nuanced conflict. This could have been done by tying in some of the later themes but keeping the industrial setting and aesthetic. For example, you could have circumstances where technological progress and advances are starting to "equalize" the world regardless of what benders want. Firearms and other weapons could have emerged as an element of the story that obsoletes bending, paired with technology starting to sever the connection between benders and the spirit realm, weakening their powers. The fading of an era and the death or obsolecence of magic are two themes I love explored in a setting, and Korra could have explored both.
I also like the idea of a world which doesn't want the Avatar anymore, and a story about Korra coming to realize she's an anachronism could have created a compelling story about self worth, belonging, and the passage of traditions. A narrative that sidelined the Avatar and slowly but surely made apparent the politics of the new world, and the Avatar's increasing irrelevance in the grand scheme of it all.
The whole thing should have ended with the equalists still active, power in republic city shifting to non-benders, Kuvira winning the war in the earth kingdom, the fire nation starting to do imperialism again, and a new, terrible global conflict implied to be coming. Korra should fail, but accept it and achieve an understanding the other Avatars didn't, ending the cycle of the Avatar and accepting the cycle of history.
