I watched the prequels again a few months ago. Sure the dialogue is clunky and the acting iffy but the world-building was stellar, the intrigue around Palpatine was fantastic (he was the star of the prequels for me). What killed the films was reliance on CGI that wasn't ready yet and which people didn't really know how to work with, and nobody tightening up the dialog - in the OT the cast said no to George on a number of lines. Without George Lucas it's not Star Wars.
I actually have found that the new trilogy has left me quite strongly agreeing with this.
Whatever people want to say about the prequels it's still really cool that those 3 movies are Lucas' vision. I'm not going to argue that they are good movies.
When Luca says "they are supposed to be for kids" the usual argument is "well why is there decapitations and conversations about trade disputes". However, I think this just means that he set out to make a kids movie but put in some things that don't really belong. He was still trying to make a movie for kids.
Anyway, that's not the point.
There is plenty of great Star Wars content that was not made by Lucas but these were always really side-content that allowed the OT to stand entirely on it's own. Some of the best books are set literally a thousand years before the events of ANH.
When the prequels came out they did start to mess with this a little bit by having side novels and cartoons but again those were distinguishable from "real" Star Wars.
The plan for these movies originally was having the 3 directors creating 3 movies that would form a trilogy. Except they had no real plan for that trilogy and it seems they were just intending to let the directors all do their own thing. They are basically "Star Wars" branded movies. They are not really Star Wars movies.
At least with Solo and Rogue One they had the decency to put them under the "A Star Wars Story" banner and allow them to be their own thing to some extent.
With the main trilogy though they are trying to pass these movies off as the continuation of an epic story but really they are cheap knock-offs masquerading as legitimate sequels.
This is especially true for TLJ where it's almost like they legitimately thought that doing something completely different and off the wall is a good idea when you are sitting on episode EIGHT of a nine part series.
TLJ is Rian Johnson's take on Star Wars but it isn't Star Wars.
You telling me if I sit down over the next 18 months and write a new book titled "The Lord of the Rings - The One Ring Reforged" as a sequel to The Return of the King then I can just pass it off as a legit entry in the series?
The only difference though is that the Tolkien estate would not endorse it whereas TLJ is passed off as "official" because Lucas sold the rights.
Let's say in theory I was able to get over that hurdle though. Maybe I bought the rights.
So in my new LotR book it turns out Sauron is back and the ring is back.
Saruman didn't die either and his grand-daughter is going to go into Mordor and steal the ring from Sauron and use it to bring peace to the world forever. Aragorn tries to advise her against it but he is a weak old man now so whatever. Blah blah blah.
So people are just forced to accept this as "a bold new direction" for LotR under threat of being called racist or sexist or whatever?
People who point out that this is NOTHING like LotR and it not only undermines the originals but changes main characters in an inconsistent way are hit with "you're just angry cos you have rigid ideas and they subverted expectations".
It's fucking nonsense.
Where the sequels fail for me is that they have no sense of authenticity.
It's fine to "subvert expectations" in the sense that great twists and surprises in movies are awesome.
It's not fine to significantly alter the nature of something just to say "I am trying something new".
In other fields, most corporations understand this and protect the authenticity of their brands by releasing new ideas under different branding.
With Star Wars it's been more like they try to pass these copies off as authentic Star Wars movies and they have an army of hacks ready to berate customers who are saying "this isn't how Luke Skywalker would behave" and pointing out how inauthentic the whole thing is.
Then, in the end, the same people who were claiming fandom is toxic and is just mad because TLJ tried "new" things had a hissy-fit because the next episode did things that they themselves disagreed with.
"Your TLJ criticism is dumb because you just didn't get what you wanted it's all about the themes maaaaaaan. I didn't get what I wanted from ROS but it's OK when I complain, my criticisms are valid." Bunch of fucking two-faced hypocritical cunts. When does the Rian Johnson fandom get it's turn to be called out?
The trilogy has been absolutely dragged down by arguments over the directors and seemingly also by disagreements on how the movies should go. Shit, they even dumped the director of 9 and replaced him with the director of 7 who then went to work undoing the ideas of the director of 8. What a fucking mess. All the while pushing ideas about "russian bots" and conservative white dudes being the only ones who dislike the movies instead of just doing good movies.
At least with Lucas in charge the movies would maintain their authenticity even if they were poor movies.
