I think choosing to create a Sequel Trilogy kind of raises the question of what needs to be resolved that wasn’t resolved in the Original Trilogy. The OT only resolves the ideas of “balance” and the Chosen One retroactively, since those ideas didn’t exist in the OT.

Regardless of those issues, the Sequel Trilogy we got sort of had the right ingredients for an interesting question to resolve. Obviously one plot point could’ve/should’ve been focused on challenges of running a government after a revolution. But as far as the force side goes, I think you could have still had a Solo child fall to the dark side, and Luke go into exile searching for answers. Maybe Luke could discover how the Sith actually were an offshoot of the Jedi, and now he is seeing history repeat itself with his fallen student. The same mistake is being made, but how can he prevent balance being lost? And this could bring up now Luke’s new Jedi order would be different from the old. Anyway, a lot of interesting ideas that could’ve been played with.
