Having the main hero humiliate the main villain in part 1 of a 3 part story was the critical mistake. You can’t have a standard hero’s journey and have the villain straight up lose 1/3 of the way in. It doesn’t work with audiences to establish the antagonist as a credible threat to the hero. To empathize with the hero’s struggles, they have to actually STRUGGLE and grow and learn.

Now, if Star Wars were a more cerebral and genre-defying franchise, that’d be a different story, but it’s not. The people want your familiar hero’s journey, and when they don’t get it, they get confused and dislike the feelings they get.
