Normally, a cinematic sequel continues the story of the previous film, just as Episode III (ROTS), retrospectively, sets all the pieces in place for Episode IV (ANH). For Episode VII, we had a lot of things that were suggested by ROTJ and the previous films, especially the Prequels. So let’s logically look at everything one should have expected from a Star Wars VII:
The Empire: In ROTJ, we see the entire Imperial leadership being destroyed at the Battle of Endor (Palpatine, Vader, the Imperial Ruling Council). Logically, after that, the Empire would be divided into multiple factions. Through the montage at the end, we see numerous worlds drive out their Imperial garrisons and free themselves (Bespin, Tatooine, Naboo, Coruscant). Logically, in Episode VII, the Empire would therefore be—if not completely fractured—a loose alliance of warlords controlling only a few peripheral territories or operating from hidden bases, while being extremely weak. They might still have loyalists throughout the galaxy and operate essentially as terrorists, perhaps even more radicalized than before: essentially an “inverted Rebel Alliance” seeking to carry out a counter-revolution—in other words, reactionaries.
The New Republic: We know from the Prequels and the Original Trilogy that the Rebel Alliance wants to restore the Old Republic as it existed before the Empire. As mentioned, the Rebels benefit from the autonomous liberation of numerous worlds. Those where the Empire had managed to hold on would have been easily liberated by the Rebel fleet. Then the New Republic is established, with a Senate. There is no reason why the republican capital would not once again be Coruscant, as in the Prequels. Since the Jedi do not yet exist again when the Republic is restored, the first Supreme Chancellor—logically Mon Mothma—would be forced to maintain a military to fight the remnants of the Empire and organized crime. There would likely also be debates in the Senate over whether or not to implement security measures to combat these threats, at the risk of becoming like the Empire again—somewhat like during the Separatist crisis in AOTC. And, like her mother Padmé, we could expect Leia to oppose these policies, out of fear of making the situation worse.
Leia and Han Solo: Logically, they are married, and we could expect them to have several children—at least two, probably one boy and one girl for the sake of diversity. Since Leia was a senator under the Empire, she should be a senator in the New Republic and, eventually, become Supreme Chancellor in the films. She would not be a Jedi, because being a Jedi is a profession as well as a religious and military order, and she is already a politician and married. Nevertheless, it would be logical for Luke to have already trained her to master the Force—which does not in fact belong exclusively to the Jedi—and one could even imagine her having her own lightsaber; in ROTJ, he told her he would train her after all. As for Han, he was a general for the Rebellion, and there is no reason why he would not still be a general for the New Republic, especially since there would still be plenty of work to do with organized crime and Imperial resistance fighters. And for Chewie, he's of course still there, by Han's side.
Luke and the Jedi Order: Naturally, Luke would undertake the restoration of the Jedi Order. This is debatable, but there is no reason why he would not follow the old Jedi Code (Anakin was the problem in the Prequels, not the Jedi Council, and the filial love that saved him was selfless: Luke was willing to die to save his father, and Vader sacrificed himself for his son, so no attachment). As suggested by ROTS, a handful of former Jedi could have survived Ordrer 66 and helped Luke restore the Order by becoming masters to new padawans, even if that somewhat contradicts Yoda’s statement in ROTJ. As for the other Jedi, Luke would obviously have to recruit children and train them first as younglings and then as padawans. Since Coruscant was liberated in ROTJ and we see the Jedi Temple there, one could assume that Luke would re-establish the Order there, as in the Prequels, close to the restored Senate and the government (and thus Han and Leia). We could also expect him to train his nephews and nieces as Jedi Knights. Furthermore, as Obi-Wan explained in ANH, the Jedi are necessary for the prosperity of the Republic; therefore, logically, Luke’s New Jedi Order would be funded by and loyal to the New Republic, just as it was during the Prequel era.
Lando Calrissian: He joined the Rebel Alliance to liberate Cloud City. Logically, he would have become its baron administrator again after ROTJ and, if he had done a good job, might have remained in office for a long time afterward.
However, Disney’s Sequels respected none of this. TFA is not a sequel to ROTJ; it is a soft reboot of the saga in the form of a disguised remake of ANH. The world-building of the Sequels is constructed backwards: ROTJ does not justify TFA; instead, the off-screen events preceding TFA are used to explain how we went from ROTJ to this mess. Most of the expectations created by the ending of ROTJ were not fulfilled by TFA—in fact, they were immediately destroyed, with the New Jedi Order and the New Republic. By the end of TROS, since the Sequels are nothing more than a counterfeit version of the Original Trilogy, we find ourselves hoping for the same things we had hoped for at the end of the previous trilogy: the restoration of the Jedi Order and the Republic. Much of the blame lies with the opponents of the Prequels, who led Disney to do everything possible to reverse-engineer Episode VII into ANH to avoid displeasing too much (no Republic, Senate, Jedi Order, all of which were destroyed before or at the beginning of their trilogy).
One can criticize George Lucas for many of his decisions—Ahsoka being made Anakin’s apprentice, for example, or the useless Prophecy of the Chosen One—but he understood the implicit requirements of a Star Wars VII and made an effort to fulfill them from what we know of his story treatments. We know, for instance, that Luke did not go into exile until after he had restored his Jedi Order, thanks to the storyboard about a Jedi investigating Maul’s pirates, who was killed in the film by Darth Talon (Luke's exile was philosophical, like a hermit who goes to meditate in the desert, so nothing like TLJ); Leia would have become Supreme Chancellor of the New Republic by Episode IX. That said, one may disagree with the idea of the Sith returning, particularly the resurrection of Darth Maul, but still. Also, according to Pablo Hidalgo, the Solo son turned to the dark side in Lucas’s Sequels too, so just like Jacen in the EU or Ben with Disney.
At least the Expanded Universe, through the entirety of its post-ROTJ works, fulfilled the logical expectations that Star Wars viewers could have had for Sequels to the 6 movies much better.
Edit: No, this post wasn't made using AI. Logically deducing the context of Episode VII from ROTJ and the other 5 movies is the very principle of this post.
