As much as I appreciated what NATLA was trying to do and think it is worth a rewatch, can I just say as an unapolagetic Yue stan that they completely ruined her, and Yukka by extension.
And say whatever you want about her scenes leading up to the sacrifice (which did make me cry, I'll admit, her speech about living was actually a nice addition), but it was actually this line that left me absolutely seething and in my opinion proves that the writers completely misunderstood what made the sacrifice so powerful:
I actually had to pause the television and collect myself after this one because holy fuck is this the stupidest thing I've ever heard. The entire point in the animated show was that she didn't get to make her own choices before this point. She didn't get to choose who to marry, she didn't get to choose her role in society, she didn't get to choose basically anything about her life besides maybe how to style her hair or something. Yue was a character who was extremely dutiful, but also extremely boxed in by her duty. It was both her greatest strength and her greatest weakness, a parody of itself, just as her mere existence was a parody: while she was saved by the moon spirit as a child and allowed to live on, it was that very reason that she eventually gave up her life. And the very fact that she was given these choices in the first place in the LA seriously undermined the idea of her sacrifice. Yue was told her entire life what to do, and although she did manage to find a bit of freedom through her brief romance with Sokka, ultimately, she still didn't get to publicly be with him or reject Hahn or anything similar. Her sacrifice was what she saw as her duty, yes, but her sacrifice for her people was also a way of standing up for herself and finally resolving to make her own choices. In that moment, she not only saved her people, but she finally made a decision for herself instead of doing something someone else told her to, even going against Sokka's wishes to do what she thought was necessary. So in the LA, with her having a place of influence in her community, with her being able to call off her engagement, with her being told that she could one day be chief, to that stupid fucking line implying that she was in no way ever repressed and free to make her own decisions the entire time, removing all of her character growth and any character significance to her actions, it was all basically pointless. It made Yue into a plot device for Sokka to bond with and to move the Aang-and-Kuruk plotline forward. In the animated series, Yue was not a plot device, and she was extremely well written, whereas in NATLA, her character fell completely flat. She talks about responsibility and pressure in her first scene with Sokka, but other than that, she has no depth. In other words, she has no depth besides her relationship to him.
Anyway, I hope we can all agree that her characterization and a lot of the decisions made in the last two episodes of NATLA were nothing but a pile of bulshit. From Iroh killing Zhao to Yukka having zero chemistry to Katara just magically becoming a master to Zuko being shelved to the plotline about Aang not feeling like he belonged having absolutely no buildup beyond a throwaway line in the second episode to everything about Yue I spelled out above, I would go as far to call it just plain bad. Again, I'm glad it got renewed, and I'll be the first to say a lot of other episodes get unnecessary hate, as well as that we are working with slightly different characters (especially Azula) in this version than the first, but I was really disappointed with seeing Yue in LA for a second time.
