Here’s my perspective on that question:
Episode IX was a cool movie. It had visual appeal, great acting, a complex plot, and emotional intensity.
But it had a really high standard to reach for, and some just don’t think it got there.
I think one problem was that the makers lost Carrie Fisher and had to do a lot of rewriting. I don’t really know a whole lot about the production process, but that could definitely be an element.
Episode IX also had some inconsistency with the previous episodes, and just Star Wars canon in general.
I can’t say a whole lot else without spoilers.
Overall, it was a good movie and definitely not a waste of time, but I can see why some people would be dissatisfied. Some of them were probably looking for the thrill that the original trilogy gave them, but something as nostalgic as that just can’t be recreated.
What I know in my head and what I believe in my heart are two entirely different things.
