The Star Wars Prequels were about the Republic and Jedi Order's downfall, The Original Trilogy, the middle part of the story was about reclaiming what had been lost...
The Sequel Trilogy should have been about a revitalized Republic, and Jedi Order facing a new threat, or even the vestiges of Palpatine's Empire, but in that case the Empire should have been the insurgents, not "Resistance" as there would be no such thing since the Republic would be functional and not destroyed in one fell swoop... Instead we got Sequels Showing us, our original heroes, actions were all in vain. They were depicted as failures, and cowards.
Here's how I would have broadly done the Sequels.
Opening Scroll:
The Force Awakens...
LUKE SKYWALKER, JEDI Master is missing! His sister, Chancellor of the New Republic Leia Organa Solo, has taken up the mantle of their mother Padmé Amidala, and united a once war torn galaxy in peace.
Yet darkness rises. Snoke, a darkside force-wielder has unified fragments of Palpatine's old empire and they've begun to wage war upon the New Republic with his warlord, the mysterious Kylo Ren leading Snoke's armies in an extremely effective assault...
Desperate, hoping her brother will have means to combat these two new Dark Lords, Chancellor Solo, sends her niece - Kira Skywalker, a fully trained Jedi, with Han, and Chewbacca in the Millennium Falcon to locate Luke Skywalker, lost while seeking out a long forgotten Jedi Temple...
OK this is only a quick rough draft of the scroll, intended to give the general notion of what these three movies should have been about.
Here's what we would learn along the course of the trilogy.
Snoke is a Whills, entombed as punishment for practicing dark force use, and he has been influencing events for some time now. Including manipulating both Darth Plagueis, and Palpatine. We also learn before his entombment, Snoke was known as - Skywalker - And the Skywalker family took their name from the myths surrounding this dark Whills. It will come as little shock that Snoke, created Anakin Skywalker from afar...
We learn that Kylo Ren is really Ben Solo who was thought dead while on a Jedi Quest - But what really happened was he came across Snoke's tomb and awakened the dark entity, which seduced him to the darkside.
By the end of the first film, Luke, Han, and Leia are altogether and ready to face Snoke. Kira Skywalker has made a new friend in a Stormtrooper she helped defect from Snoke's insurgent Empire.
In this version of events, there is a fully functional, yet reformed Jedi Order, and of course the Republic is almost fine.
By the second film, Kylo Ren would be turned back to the light thanks to his cousin Kira, and uncle Luke.
And in the third film, it would be Luke, Kira, and Ben all facing off against Snoke.
We would learn Luke discovered the full history of the Whills, including the one known as The Skywalker - Snoke.
Keep in mind this is all broad strokes, but the idea here is not to reset what the Old Trilogy did, and show that our old heroes made lasting achievements.
