Well, they could, you know, actually do fairy tales from other countries.
Ya know, do fairy tales from Africa instead redoing shitty remakes of european fairy tales and then color washing them so you can call all your critics bigots.
Show us some of that cool African Fairy Tales. Instead of making the Little Mermaid black, why don't you look up the folklore about the fresh water fairy tale from Brazil? It's just similar enough to get you something to work with, just different enough to not be derivative.
Tons of stuff from other countries. All you have to do is hire or train good writers and boom-instant cash!
Oh yeah, and do what you should've started a long time ago:
KINGDOM. HEARTS.
Give it the MCU treatment, there's a lot of convoluted storylines to get through, but you can work it out.
