As I said in another thread (or maybe early in this one - I can't remember), I see pretty much everything after the original trilogy as a diminishing of Star Wars. There were ups and downs, but nothing made Star Wars better - and the sum total was a diminishing effect that has really marred the greatness of the original story. It was trying to squeeze yet more juice out of an increasingly dry lemon. IMO. This, as opposed to Star Trek which, despite the expected highs and lows of 60 years of film-making, was able to continually remake itself while still remaining true to the original vision.
I think the primary "error" in everything post-OT is that the OT was, first and foremost, a MYTHIC STORY. It was a heroes journey writ large in an epic universe, populated by very human people who became heroes (or villains). Everything after lost sight of that.
The prequel trilogy became lost in its fascination with effects and world building - with techne (ironic, considering the arc of the central character, Darth Vader). There was some beautiful visuals and set-pieces, but the story and characters were lacking in vitality (not to mention the acting). This is perhaps best exemplified by Darth Vader being reduced to the "I hate you!" moment. .
The recent trilogy not only lacked George Lucas's genius for cinematic worldbuilding, but also lost any sense of mythic vitality, becoming a pale simulacrum of Star Wars mythology. Like Rings of Power, it seemed like high budget fan fiction made by people with no real sense of the original vision and mythology.
Just about everything else felt like unnecessary filler - niche stories without the mythos or heart, the best of which didn't really have to be Star Wars, and whatever they offered in terms of story-telling was obfuscated by trying to be a "Star Wars story." The worst of which felt like a copy of a copy (or fan-fic of fan-fic).
Hey, you said we could complain...
