It can't go anywhere new or interesting, even the best of the EU stuff is just remixing ideas from the OT. It's a zombie franchise, just endlessly going through the motions. I kind of hate it, honestly.
One example of the OT stuff having paper-thin veneer papering over the lack of believable world-building is the clever "Evil McEvilface" type naming scheme for the Sith that runs out of options after exactly two examples. Darth (in)Vader then Darth (in)Sidious, but after exactly those two examples they ran out of ominious sounding "in" words.
That reminds me, for The Force Unleashed they wanted darth vader's apprentice to be a darth and asked George Lucas for suggestions, he gave them Darth Icky and Darth Insanious, and never discussed it again. Everyone complains about Disney trashing the EU, but Lucas hated the EU and didn't bother to disguise his contempt for it.
The first order is another good example of the complete void of creativity that Star Wars is. The empire is defeated and the republic is restored. A new imperial remnant is trying to restore the old order. They have an interstellar superweapon and giant spaceships and the people fighting them are the "resistance." Why? Why is the republic still "resisting?" They're the status quo now! This should've been a reversal of the old formula, where the first order is small and weak, maybe one of many imperial remnant organizations that the republic is slowly taking out with their superior forces, and maybe they pull some clever coup (clever meaning not an insterstellar superweapon to just automatically win) to put the republic on the defensive.
Instead it's just the same shit as before. It's always the same shit. It will never be anything different. Star Wars has nothing new or interesting to say. The OT was a fluke, mostly carried by Empire, and with a few rare exceptions (also flukes) the rest is just endlessly remixing the OT's ideas without the soul that made it work.
So like any proper star wars fans, we all hate star wars, and like any proper star wars fans, we have ideas for how we would've done the prequels/sequels. So what are they, show your cards.
If Disney held a gun to my head and told me to outline a reboot of the sequel trilogy, I'd do the above. There's dozens of remnant forces, planetary governors and admirals with a few ships and a couple planets still holding out, and the Republic is slowly clearing them out. They've got a new giant ship, equivalent to the giant ship in TLJ, which they keep in orbit around the Republic homeworld and they're always arguing over whether or not they need it. Leia is chancellor. The first order, under the cover of insignificance, has been using Snoke and Kylo to unite the remnant forces, and they infiltrate the Republic military, seizing control of the Big Ship and invading the republic homeworld in one big coup. The B-story is the republic forces suddenly thrown into this brutal urban war for survival.
Meanwhile in the A-story, Rey is an orphan on a backwater planet, working as a thief and intuitively using the force. She meets Luke who's passing through on a mysterious errand, and manages to steal his lightsaber. When she goes to fence it, remnant agents in the criminal underworld recognize it and send word back to the First Order, who's looking for Luke. They also try to capture Rey, who uses the force to escape. Kylo and the Knights of Ren go to find her and the lightsaber. Finn learns about this plan and steals the transmission, using it as a bargaining chip to defect, for the same reason he defected in the original. Poe doesn't trust him, Leia has the force and knows he's trustworthy/force sensitive himself, and she sends Poe and Finn together, along with a small crew, to find Rey before the Kylo gets to her. They kind of hate each other at force, but Finn uses his stormtrooper credentials and knowledge of how they operate, Poe uses his piloting skills, they learn to trust each other, become friends, maybe fall in love (maybe that's why Leia made them go together), make Disney put their progressive money where their progressive mouth is and stop tiptoeing around it.
So plots converge there, Han also shows up and meets Luke for the last time, the scene we didn't get in the original, Kylo kills him and they go on a race to find Luke.
Turns out! Luke has become disillusioned with the force, and in an echo of Darth Vader's "bring order to the galaxy," has decided if people can't use the force for good, no one can have it anymore. He wants to sever the galaxy's connection to the force, somehow. Maybe merge with the lingering remnant of palpatine, the feedback shattering the force, maybe find some force nexus on Korriban or some similar planet, who knows. Second movie something happens. Kylo fights Luke, gets his ass whooped, but Luke refuses to kill him. They learn Luke's evil plan. Rey redeems Kylo in the third movie and he use his super TIE fighter to do the Holdo move on the Big Republic Ship, killing Snoke and giving the republic the opportunity to turn the fight around. Rey, along with Kylo's sacrifice, restores Luke's faith in the force, but he dies. Rey and maybe Finn take up his mantle to start a new jedi order. Then darth maul shows up with robot legs.
