The main problem I had with the show starts with the creators. I don't understand how two white, cis men thought that they could write a show about oppression without the feedback of anyone else. The show could have been so great, it could have been really great but they just could not get their shit together.
They were too busy trying to establish who were the villains and who were the heros that they did not even deal wit the real problems at hand like the fact that benders were in fact oppressing non benders.
I don't understand how losing bending was the worst thing that happened to these people when Aang himself used taking away bending as the humane method of punishment for benders who were actively creating problems for people that could not be handled. That was how TLA ended and that was seen as a good thing. Bad Benders + Losing Bending = Happy Ending. It was Deus Ex Machina as hell but it was the good happy ending to everything.
But in this show, Bad Benders (The first were gangsters and thugs that were actively oppressing nonbenders) + Losing Bending = BAD DON'T DO OMG! It flip flopped the entire ending of the last show and turned that into a bad thing.
When Korra goes (since that's being reblogged a lot right now) You're oppressing yourselves, that line was not challenged.
Even in FMA when Edward went all ~~~~colorblind we all bleed red~~~~, they also had in the same episode Olivier saying that differences were good, there is nothing wrong with people being difference races because that's a good thing, it's possible to work together. Fuck that we all bleed red shit, if we all think the same we'll die the fuck out up here.
There was no one to challenge the idea that non benders were oppressing themselves because they spent the whole show painting nonbenders as bad guys when really they just want the same treatment as the precious benders that get all the jobs and get treated like heros even when they are lying cheating snakes.
and on some more about my thoughts on this show but that's my main issues at this moment.
