The very boring political intrigue in the prequels didn't match the tone of the original trilogy, but I could look past that if the main purpose of the prequels had done its job. Jake Lloyd was an absolutely atrocious Anakin (Haley Joel Osment post-Sixth Sense would have made a much darker and better character...and it would have kept his career afloat), and Hayden Christensen is cringe at its finest. Even Natalie Portman is rendered a terrible stage actress having to vocalize the terrible dialogue that Lucas made her attempt to recite. Add to this the fact that the prequels look too shiny and clean and really divert from the "lived in" look of teh original trilogy, the reliance on CGI as a character, and the awful acting by just about everyone (Ewan and Liam are ok with what they have to work with) and there is absolutely nothing believable throughout the prequels. The especially painful "Noooooooo" that Vader unleashes is so laughable that it makes even the most redeeming prequel film a giant mistake as it completely fails to stick the landing and turns the iconic Vader into a comic relief character.
Many of the folks who hate the sequels grew up on the prequels and never had a problem with them. That disconnect is so great and it shows that the Star Wars universe will forever be divided, both in story and out. That's actually probably a good thing as both fanbases can be appealed to and appeased in the years to come and even the two halves will have casual viewers between both that will simply increase overall profits and ticket sales. The OP suggest that the Star Wars universe is dead...wow, that's about the most incredibly backwards thesis I could ever imagine. Sure, there isn't much hype in the universe right now, but that's also because we don't have anything to be hyped about yet. Just wait until we get another teaser trailer and watch the internet go crazy, in all manner of ways, of course.
Well, I watched the prequels first and love the political tone. And I do look the original movies, but to me it's too "rebels take down an evil empire" vibe, whitout much thought about everything that is happening and too maniqueist. Rebel alliance = good guys, always doing the right moral choices and etc and empire = bad guys that just are bad and want power.
The prequels added depth to star wars lore as a political setting and showing the Empire was an evil force that came from a degenerated and corrupted republic. Rogue One showed us the rebels weren't an united organization and they did many questionable things, mostly because they had no other option in front of an evil empire, but they did nonetheless.
The Mandalorian is showing us the galaxy post empire fall and how the new republic is pretty much a bad joke to the common folk.
I think star wars grows when it goes off the way of Skywalker stuff. Leia and Solo stuff. I love the world building of the franchise.
