Fans seem to forget that up until like as far as I 'member the very last battle against Ozai, Katara & Zuko weren’t even friends! Katara literally hated him and even when all of her friends forgave him she still didn’t. & not in a cutesy love/hate tsundere way either. & the best friends to lovers trope just doesn’t have the same angst, even tho is healthier and sweeter to watch. They talk about Kataang being stereotypical because “hero gets the girl” but Zutara is an overdone trope in all media.
Literally, where are you getting this. No one ‘forgets’ that Zuko and Katara were not friends until the end of The Southern Raiders, but fans like you seem to forget that episode didn’t happen in a vacuum! The Southern Raiders was the culmination of a relationship arc which spanned the entire series. It didn’t just come out of nowhere, and it wouldn’t have been possible without the episodes that had come before it, especially the Cave of Destiny where Katara showed Zuko compassion and trust and he, in her eyes, threw that back in her face and betrayed her and his own uncle.
Which, likewise, hadn’t happened in a vacuum! It was no accident that Zuko and Katara were paired up in every season finale, that their narrative journey parallels the story of the Cave of Two Lovers, that Katara first tried to show compassion to Zuko and his uncle by offering to heal the latter only to be driven away by Zuko’s own pain and anger. Then, when they were trapped together in the crystal caverns beneath Ba Sing Se, they had a moment of understanding and true empathy, which wouldn’t have been possible without the narrative beats their relationship arc had already hit to that point.
Katara didn’t forgive Zuko until The Southern Raiders, but after that, they were friends with a deep bond--which, sure, you can interpret however you like, but the fact remains that Zuko sacrificing his life for Katara was written, storyboarded, and animated in the most romantic possible light. (Just like Katara touching Zuko’s scars in the caverns was animated with greater intimacy than any canon romantic kiss on the show, with the way the screen held there for a solid minute, slowly panning in as romantic music played, Zuko closing his eyes and standing still, letting Katara touch his scar (something he’d actively prevented a girl from doing earlier in the season), and expressing true trust and vulnerability to someone other than his uncle for the first time in the entire series.) The fact also remains that it is Katara who Zuko chose to go with him--and Katara who accepted without reservation, despite the boy we’re supposed to believe she was already in love with, and even her own brother, were headed off to very different locations, with no guarantee that any of them would see each other again.
It’s Zuko with whom she chose to spend what may well have been her last day on Earth. It’s Zuko who saved her life, making the easiest decision he made in the entire series, and whose life she saved in turn. It’s Zuko with whom she spent the climax of the entire series. And you want to pretend that the alleged ‘best friends to lovers’ ship was somehow ‘healthier and sweeter to watch’, even though that’s the ship which involved more than one kiss without consent, an assumption of Katara’s feelings, and absolutely no agency for her in her own romantic narrative (because there was nothing to bridge the gap between ‘you kissed me and I explicitly did not like it and got angry’ and ‘we’re gonna make out now’)??? Really???
Ok, anon, you do you, but I’d much rather have the ‘overdone trope’ of Fire and Water and enemies-to-friends-lovers with the full and mutual relationship arc which spanned all three seasons of the show, rather than my favorite character sacrificing her agency on the altar of the ‘hero gets the girl’ trope without so much as being allowed the dignity of voicing her own feelings.
