The original Saga is i like to think in its own pocket universe it includes, Star Wars, Empire Strikes Back and Return of the Jedi the original cuts only. And it ends on an upbeat ending with our heroes on Endor.
Then you have Universe B which includes the Special Editions and Prequels which are Lucas So called Canon 1-6 Saga of Darth Vader.
Then you have Universe C which is the Disney canon and its the Rey Saga 1-9, or Palpatine Saga.
Lucas sequels would have likely continued Universe B canon and not the OT canon. They would have indeed been a sequel most likely to those movies.
I would have liked a genuine sequel to Return of the Jedi which was an organic extension of the Original trilogy, which to be honest is kind of hard to imagine with all the EU that is out there but i wanted an original story. Not lets cut and paste the EU, make Luke without a wife or son and a prequel Jedi, and Darth Maul and some midichlorians. And rip off the entire arc of the EU with Han as a leader and a General until he gives up his commission, and Leia as President or Chancellor. And mix in Prequel Yoda training Babies but instead insert Luke. Along with Darth Maul being the Prince Xizor controlling the underworld its not original.
The only positive i think is at least Luke was a wise teacher in those treatments and somewhat recognizable, They actually established a new republic and Luke was successful at reviving the Jedi Order. But with the Sith returning with Maul its undoes Lucas own chosen one prophecy of ending the Sith. Feels like a pretty pathetic and desperate attempt at just winging a third trilogy. I’m sure there are people who would have loved a mix and match of EU, with Filoni Star Wars and prequel for the Star Wars sequels i’m not one of them.
Admittedly the Disney trilogy has its own legion of problems. But at least i can watch and enjoy them. The effects are good, the cinematography isn’t janky and the acting and dialog are excellent while the story and characters might suffer from being half baked at least it has the general flavor of a Star Wars film i.e. the OT. I’ll give Episode I at least an honorable mention it had good cinematography when it wasn’t cgi and felt like a Star Wars film. I’ll also give Hayden an honorable mention he was good in episode III and brought genuine pathos to the role of Anakin. Something a much better actor in Adam Driver isn’t able to do with Kylo Ren.
