I honestly don’t have the braincells to elaborate properly, but Disney as a company hates and never knows how to handle Frozen and that’s super heartbreaking.
They see it as nothing but their most profitable title and in turn, every decision about that property always goes back to “never take risks too big because remember Elsa is the kids’ Superman at this point”.
Frozen II could’ve been great, but they refused to let Elsa face the consequences of dealing with her problems alone (by remaining frozen and unable to save the castle), and they also refused to let anything happen to Arendelle’s castle because they’re building it for the Disney parks.
Arendelle in KH3 could’ve been great, but instead it became a boring repetitive and senseless stage with no cohesive narrative attached to it, all because the prospect of Elsa being used for evil or doubting herself enough to become a “villain” went against Disney’s model of perfection they try to keep her on.
It just sucks how Frozen gets to have such an insane amount of creative people in its fandom, only for the actual team behind it being held back by execs who just make the property worse and not letting it reach its actual potential.
