And the problems with The Last Jedi were the kind that damaged the brand as a whole (because they signal the intent of decision makers at the top): deliberately antagonizing the core fanbase, openly going out of its way to hold the OT in contempt, prioritizing a political agenda over the quality of the story and characters, and wasting the rare (and now lost) opportunity to reunite the OT cast to properly say goodbye.
This is a problem overall and has been experienced in other franchises as well *cough*Doctor Who*cough*. The producers, show runners, etc, have been far more concerned with trying to satisfy a small segment of fans and push some agenda or message, all the while forgetting that they have to actually tell a good story too. Sci-fi stuff always waxes political... doesn't matter what you support or despise. If the story is good, people will watch or read it and keep coming back, and it will likely attract new fans too... even if you are pushing an agenda or message. If you're going to beat your audience over the head with said agenda or message every few minutes, lines, or whatever, they will get tired of it and walk away.
There's no reason for fans to think any of this has improved, even after five years of Disney being afraid to release another film.
That's because the House of the Mouse has been pooping on other franchises, hoping the audiences will forget about the first round of mouse poop on the Star Wars franchise while they work on the current victim(s).
