It’s because they’re a mega corporation that is buying up their competition, controlling the distribution and production of their films, and weakening the landscape of movies by over-saturating it with uninspired, passionless remakes of recognizable properties to avoid risk and maximize profits, causing their remaining competitors to seek to do the same, leaving fewer and fewer sincere films being made. Of course a business will want to make money. That’s a given. But the former culture at Disney was also driven by a desire to bring magic into people’s lives. Now they just want brand loyalty, market power, and enormous paychecks.
(Not to mention how unscrupulous they are about editing/marketing their films to foreign audiences in the hopes they’ll make even bigger box office profits.)
They are attempting to make movies risk-free; every release has to be a sure-fire success. That means they couldn’t care less about how the movie turned out if it does two things—gets butts in seats at the theater, and doesn’t ruin the viability of that IP. They couldn’t care less about any criticism towards, say, The Force Awakens. None of it was strongly-felt enough to drive away a large enough audience, and the film was a financial success. When films turn out like Solo or Last Jedi, where the audience is either greatly divided or uninterested in seeing the movie altogether, Disney gets worried. (Which is how you get market-tested train wrecks like The Rise of Skywalker attempting to appeal to everyone.)
Why is the early 90s commonly referred to as the “Disney Renaissance?” It’s because Disney started to put out original movies with solid animation, compelling characters, good music, and solid writing. If we ever make it out of this current version of Disney (which seems unlikely), I wouldn’t be surprised if this period were referred to as “The Dark Times”, “The Nostalgiassance”, or “Factory-Made Movies”.
