I actually liked TLJ, but this seems particularly soulless and money grubbing even by normal Disney standards. It's like awards season on steroids, two hours of Disney patting themselves on the back and saying how great their company is.
Kingdom Hearts I can forgive because it's a game and games always have multiple character skins you can play as. A movie's a completely different beast, not only in popular culture and a wider audience appeal/demographic, but in the fact that it's inherently narrative based and has to function as a story on its own terms. It can't rely solely on references and easter eggs to function, it needs character arcs and plot first and foremost.
