I think those of us who liked TLJ specifically hate TROS because putting it simply, it was designed to be the anti TLJ.
It was created partly to satisfy the 'fandom menace' (who also hate it, lol), partly Terrio's wistful 8 year old's self fan fiction, but mostly it was JJ Abrams practically yelling into the aether - or what not - that THIS is what RJ should have done, not THAT!
I'm gonna push back a little here to make sure we're still in reality and not getting carried away, cause that's not really what happened.
It was announced Abrams had signed on in September of 2017, which means it was probably some time before that. He and Terrio were working on the story for months while TLJ was still in post-production. Abrams pitched it to Bob Iger just as The Last Jedi was released. That's a fact.

Now, sure, Abrams and Terrio may have been reacting to TLJ in some ways on their own, but to say they deliberately were trying to cater to the fandom menace is probably unfair IMO, because they had already made a lot of the major decisions before TLJ was released and there was any sort of backlash. If anything, JJ himself was more on the receiving end of fandom menace hate after TFA came out and everyone was railing against how it was too much of a retread of Ep. IV.
Just calling it like I see it. A big problem with Star Wars discourse IMO is when we get carried away and start twisting things to fit a preconceived notion that doesn't really align with the facts, when it comes to the behind the scenes things and 'why' decisions were made. It's always going to be passionate and super opinionated, which is fine, but I think we should at least acknowledge the facts and not act like every creative decision we didn't agree was a conspiracy to hurt your feelings. It's no worse than how the TLJ haters acted, IMO.
Personally speaking, I was disappointed with IX, but I feel lonely in the sense that I'm a TLJ fan who doesn't really mind the broad stroke decisions (Palpatine, etc.). I just feel that it was executed in a sloppy and lazy way. That's it. I think it had a story with some epic potential and just did in a rushed, haphazard sort of way that did not carry the weight I would've hoped the ninth film in the saga would. Gonna bring Palpatine back? AWESOME. I'm there. I squealed like a child when I saw the teaser. But you've GOT to sell me on it. That opening crawl drop was...not it.
There is something poetic about TROS and its particular brand of failure. It ensured that if you liked TLJ, you would finally experience the same feeling as those who didn't.
I guess for a lot of people, but I can't say that aligns with my experience. When I first saw TLJ I honestly experienced a lot of the negative emotions that the extreme haters did. It was enormously frustrating to see Luke in that state, and I couldn't even really fully invest in other subplots because I was still having trouble processing the Luke stuff. It was jarring. The nobody reveal was also jarring, because I'm very invested in the Skywalker story. I knew that was the point and I immediately knew it was going to be rejected by a lot of people, and I even understood why. I still walked out of the theater knowing that Rian Johnson made a really good, interesting movie- but it took a few viewings to really grow on me as a Star Wars film.
With TROS, it's like I said...I just knew it felt like a subpar blockbuster. I actually went in feeling like I had a pretty good idea of where it was going (and I was right), and I went in embracing the Palpatine direction because I always felt the ST a giant Palpatine-sized hole in the villain department. It was more-so just a crushing feeling of knowing that there was a much better (probably longer) version of this movie somewhere and that this was the version we were stuck with. I'm not saying it exists on the editing room floor, but..yeah. The film gave me a lot of what I "wanted"... but not in the way that I needed it. Pulling off that balance is key. But for me I think it's apples and oranges, when it comes to my experience of TLJ and TROS. Just two very different things.
On the plus side, the score for TROS is tremendous. Credit where its due, if there's one thing we can say consistently delivered in this trilogy-- it's of course, Williams. If I want to view the ST in a positive light, it's always going to be-- we got 3 more Star Wars scores out of John Williams. Something I never would've expected.
This theme single handedly nearly salvages the film for me. Musically, it brings a lot of things together from the saga.
