This will sound nuts considering my rep regarding the DCEU, but.....at least the DCEU, their primary problem was easy to target: most of their movies sucked. SW might be in a tougher position.
With SW, as Empire City pointed out, TLJ had really good reviews. Even SOLO aka "the movie nobody asked for" still garnered OK reviews? Certainly not a critical disaster. Yet there is a problem in Star Wars land, but what exactly *are* the problems? It's easier to tackle problems or try to anyway if you have an idea of what went wrong.
