Ok, I'm gonna pop off for a bit because this has been driving me nuts for like a decade now - I'm real tired of seeing people (who either don't understand how show production works or are willingly choosing to ignore it) going after showrunner's throats when who they're really pissy with are the corporations that host those shows.
Stuff like plot, internal continuity, and character development are writing issues that can be critiqued in a vacuum, stuff like pacing, representation, and runtime are not.
If you are mad that a show was too short, that it's pacing was shitty or it's representation wasn't good enough, that is an issue with the higher ups in the network, not the writers and showrunners.
You need to redirect your anger at CN, Disney and Nickelodeon, go after them for holding animation back, and leave showrunners the fuck alone.
Do you really think that Infinity Train would end on an awkward fourth book, that Korra and Asami would only hold hands, that Legend of Korra would have such a bizarre second season, that Steven Universe would reduce it's final arc to five fucking episodes, that Gravity Falls would hide it's LBGT characters in the background, that The Owl House would end after three seasons, that so many shows would wait until their last episode to confirm their character's sexualities, if they had the choice to do something else???
Take your torches and pitchforks to capitalism's doors, not creators'.
