Ugh.
Last I checked, deep lore discussions died down, especially from the novels. Interest in more elaborate/speculative discussion, or long fanfics, was gone. Takes on Korra got more and more sexist, far more than when LoK premiered. And, more and more, people worshipped ATLA like an evangelical Bible, like it could do no wrong, with this weird cultish mentality, hence a sea of unreasonable hate for NATLA (and Korra). And even Seven Havens, before it premiered.
People (or Reddit bots) would post straight up misinformation, or flame hints of ATLA critique, like considering it anything but the greatest show of all time was taboo. At one point, I kept running into fans discussed rewatching ATLA many dozens of times, or more, yet… clearly haven’t read the novels.
Okay, maybe I’m not coming across as sympathetic here. Fandom preferences are fine. As more of a lore buff for the whole franchise, I felt… excluded. Like I wasn’t even welcome anymore.
Some of the old, sexist takes on Katara and other women being “bitches” still flare up too, but from my perspective, that hasn’t changed over time.
