>>108516051>2. Endgame canon ships usually suck and are hated. See Kataang, Korrasami, Starco. Best ships are the ones that end ambiguously.
Korrasami was hated because it was pandering and came out of nowhere. Kataang is only hated by Zutarans who are ridiculed by most. Starco was handled less than adequately sure but it doesn't have an extensive hatedom yet.
Usually, these endgame canon hatedoms form well after the show ends. One I can think of is Danny/Sam, which was pretty dominant during that show's run. Eventually, the fans of these couples having been given closure move onto something else or get bored of it, as do most of the fans of the show in general, while a few extremely vocal and militant supporters of off-pairings that didn't happen (in that instance, Danny/the niggress), skulk about in their fandom's ruins screaming to any soul that wanders by that their choice was better and that they had the support of everyone all along and hoping to God this somehow retroactively changes their bleak fate.
