Star Wars has never been about the plot. If so, ROTS would be the best movie because it’s the most complex. And A New Hope is just some weird and boring side adventure.
No one liking TROS has said they like it because of it’s plot. It’s how they make that outline into a fun movie that makes us like it. If you give it a chance and don’t enjoy it, that’s fair, but you can’t think of Star Wars as just a Wookiepedia article.
Most food is not about salt, but no salt will result in a bland and forgettable dining experience. Even if the plot is not the most important element, there needs to be a balance. Fun and good are two different things to me. A film with little plot can be fun, but a good film needs a good plot. It is the foundation of a good story (imo).
