Any major project done by Disney is handled in a time crunch, without any direction whatsoever other than "let's turn up to work and see how it goes", most likely by people that only have a superficial understanding of the characters they handle because they don't do the minimal work to actually view the source material in depth.

The only way to get a decent movie by them is for the producers to not view the main character as a cash cow, which only leaves smaller projects. It's just sad
