The biggest problem with Disney Star Wars, in my opinion, is that they lack George Lucas' visionary imagination. The original trilogy was truly visionary. The prequels, while crappy in other ways (mostly around Anakin's actors, lack of romantic chemistry, annoying details like the Fetts from downunda, Jar-Jar Binks, etc), still had the Lucas touch for world-building. They still felt like Star Wars, if the equivalent of a rock bands later albums that aren't as good anymore and lack the vitality of their youth, but still feel like the same band.
The Force Awakens was a fun movie, but to me it felt like the film version of fanfic. It didn't feel like Star Wars, but a fan's take on Star Wars. It felt over-produced, like it was the result of an AI algorithm assessing what people want out of Star Wars in today's cultural context. Still, it was overall it was enjoyable.
Rogue One was well done and also fun, although it didn't have the mythic quality of the Lucas films. But it did what it intended to do quite well.
As for The Last Jedi, I left the theater with the thought: "That was a bad movie, I didn't enjoy that very much." It was the first time I watched a Star Wars film and actually was glad when it was over. But I won't go into details, because it seems that any criticism of this film is automatically interpreted as based on some combination of misogyny, racism, nerdrage, alt-rightism, etc.
I will say that one thing that bothers me that I don't hear mentioned is the under-usage of Oscar Isaac, who in my mind is one of the best actors of his generation. He really could have been the Han Solo of these films, but seems too...tepid? It is almost like the directors said to him, "We kind of want the handsome, roguish thing like Han Solo, but don't be too roguish." I'm not saying he should try to be Harrison Ford, but he should certainly be Oscar Isaac. Maybe more of a melancholic brooder.
Solo was OK and probably overly maligned. I liked it better than TLJ. But the problem is not as much that it was a bad movie, it wasn't, but that it continued the process of "fanfication" of Star Wars. It didn't feel like the "real" Han Solo, perhaps because the actor didn't quite play him edgy enough.
One more thing. Disney Star Wars has crappy villains. I love Adam Driver in Indie films (e.g. Paterson, What if? etc) and he made Girls watchable, but he is terribly miscast and I can't shake the Darth Emo nickname. In fact, his best moment as Kylo Ren was in that SNL skit. Snoke was just a pale mockery of Palpatine. Compare them to Darth Vader, arguably the greatest film villain of all time (do you remember his sheer presence when you were a kid?!), and the truly malevolent Emperor - not to mention secondary villains like Jabba, Boba Fett and the other bounty hunters, etc.
