Jumping in because there's a point missing here. The prequels were poorly acted and poorly made, however the lore and the plot of each film were very good. Nearly all of it fits like a puzzle piece with the original movies (sans Leia's memory of her mother). Think about it this way, if you describe the plot of each prequel, they sound like they would be amazing:
For example:
TPM - The Sith reveal themselves, create a political quagmire around a peaceful planet leading to war. Meanwhile the Jedi encounter the Sith for the first time in 1000 years, both sides spill blood, and the child that would become Darth Vader is thrust into action before he can understand what's happening. World-building exposition includes the background of galactic politics, what the republic looked like before the empire, and set up that there is a large contingent of Jedi closely tied, too closely tied, to galactic politics. We see Jedi and Sith in their prime and powerful.
That sounds amazing IMO. I just wish someone other than George Lucas would have directed it and written the dialogue, as the film comes nowhere close to the quality of the plot synopsis.
Now for the sequels - they tell repeat stories, mess with lore (Why didn't Obi Wan just force heal Qui-Gon's lightsaber wound?), and overall just don't make any sense. TFA was a good reboot, TLJ was a sophomoric dud, and TROS is one bad Deus Ex Machina after another through an insane plot at breakneck speed so you don't have the chance to think about how each scene didn't make any sense. Then it ends in EXACTLY the same place as ROTJ, just 30 years later with new characters. No new lore, no plan, terrible storytelling. Great visuals though.
IDK, if they could have ended TLJ on a cliffhanger when Ben reaches out his hand to Rey and it just cuts to credits there, it might have worked better. I read through the script for Duel of the Fates, the Colin Trevorrow version of Ep IX, and while it's not outstanding, it made much more sense in the greater lore of SW and would have at least stuck the landing of the trilogy.
If they ever decided to do a modified version of Timothy Zahn's Thrawn Trilogy of films with new actors and say the sequel trilogy is no longer canon, I'd be the first in line. It feels like the Mandalorian is already going in that direction, which is great. I'd love to see more of Jedi Master Luke and his adventure
