Finished the live action ATLA. Honestly? I actually really liked it, more than I thought I would, and I wasn't even particularly skeptical about it.
I liked Katara and Sokka's dynamic here actually better than I did in the cartoon. Maybe I would be more attached to Katara being parentified in the cartoon if it was ever resolved in that show, but it wasn't, so I'm fine with it being discarded and taking a different angle with her characterization and relationship with her brother.
I have no complaints about the performances given by the actors (though I do agree with the criticisms of casting light-skinned actors for Katara and Sokka, I still enjoyed the performances, though I know I'm coming from a place of being, like. White. With that--like, people with darker skin might have a harder time enjoying the performances despite that and that's valid).
However, Dallas Liu as Zuko was a highlight for me, he absolutely killed it in every single scene. Easily my favorite casting choice in the whole show.
I also really liked bringing in Azula earlier and not making her just like a demon child who enjoys being evil. The golden child-scapegoat dynamic between Azula and Zuko even as they've been separated for years is interesting and I liked it. (In particular I never liked how Azula in the audience of Zuko being scarred just smirks, so I like how in the LA she clearly has more mixed emotions about it. To me she looks morbidly fascinated and afraid at the same time, which feels right to me.)
I thought the show did a good job of covering the most iconic s1 episodes within their limited time frame by tying them into a connected plotline with each other within Omashu. Also I know the secret tunnel ep was s2 not s1 but I think it worked for this plotline, and I liked that it centered on Katara and Sokka's sibling bond instead of a forced k/ataang moment. (I don't care for that ship but Aang antis do not think I am one of you!)
As for the Sokka no longer being sexist thing: I don't know why we're pretending "Sokka being sexist in episode one, meeting a woman who fights good three episodes later and immediately changing him mind and being normal for the rest of the series" is like some huge plot point that Sokka's character falls apart without. The live action is only eight episodes long, it can't cover everything and I'm fine with it looking at that non-arc and going "yeah, that's not fundamentally necessary." He still felt recognizably like Sokka to me.
(Also others have pointed out that misogyny is cultural and we don't really see much if any sexism in the SWT aside from Sokka, certainly not to the level that Sokka exhibits in ep1, so it's kind of an odd trait for him to have to begin with. Like he just decided independently that women aren't as capable as men? Bruh.)
But yeah, I actually really enjoyed it and I hope we get a second and hopefully third season.
