This is so complicated for me. When I first saw TLA, I think, Katara easily became my favorite character. Also after rewatching series for many times, it didn`t change. And now, after almost ten years, watching again and I can`t find her likable anymore... I don`t know what is it, but something makes me find her kinda annoying. And, the further I got into watching series again, the more it became sure how my opinions have changed. And I don`t like that, because now I have new favorite and it doesn`t sit well with my nostalgic memories of watching these series for the first time. :/

Same here actually, but reversed. I used to really hate her a lot. But as time went on I just stopped for some reason. Ngl, she's still my least favorite (next to Ozai) but I don't really hate her or even dislike her anymore. It wasn't even after re-watching it either. I don't know what changed. Maybe it's the the whole Azula fandom vs Katara fandom thing is done with. In general Katara fans are a pleasure to be around, which always helps sway me with a character. More so though, it think it was more or less realizing that I don't really hate any of the characters except for Ozai.
