I believe the sequels are made for people who didn't like the prequels (which have a worse reputation than the originals), and in that regard, they're well made so far. I don't love any Star Wars film personally, but I recognize the significance of the franchise and it's easy to see how big a departure the prequels took from the originals. It's obvious that would make some angry, given the worldwide popularity of the originals. I liked TLJ when I saw it once in the theater. I found it mostly fun and the twists were genuinely surprising to me. But that was also a departure from what is expected from the franchise, and that was always going to anger some people.
Even if it was a bad film, I think the troll-brigade internet hate machine has done far more damage to the franchise than any bad film ever could, seeing agendas everywhere and getting outraged because people online will listen to them if they have the most extreme opinion. If their goal is to make everyone hate talking about Star Wars or to stop more films from being made, it's nearly achieved. Nearly.
You can dislike well made films, you can like poorly made films. In my opinion, the prequels are poorly-made by a director who lost love of the craft and got too involved in the business side, whereas the sequels are well-made by hired directors who are only there to get the films in the can.
I don't love TLJ, and it is not my favorite Star Wars film. If you just don't really like the idea of Luke almost killing Ben in the flashback, I get it. I don't agree (people make mistakes, he died a selfless hero, that was my take) but I get it. If you think it's too long or the space chase was a silly plot device, I get it and also I agree. However, if you hate Rose, Holdo, and Rian Johnson, but don't hate Padme, Mon Mothma, and George Lucas respectively for nearly identical reasons, I don't get it.
In the end I think the franchise is better for having TLJ. I finally don't know what's going to happen in the next Star Wars movie. I haven't been able to say that since I first watched the originals. When the prequels came, we knew where the chess pieces would all land. When TFA came, we knew Disney would likely retread old territory to capture the 'look n feel' of the originals. Then TFA set up certain mystery-box questions, which we figured would be answered in TLJ. So without new questions, all that's left is, what happens next? Or, even more interesting, how does it end? I think either of those questions is more fun than any mystery box answer would have been. That's my take, pretty much unchanged since TLJ released.
