This isn’t really ground-breaking and is close to what others have suggested. Rather, I bring it up not as a new idea, but to point out the advantages of this “picture frame” for which others have/will use to present their pictures. Anyway, here goes: It’s shortly after the events of the RotJ and the New Republic is being formed. There are many factions as everybody has a different opinion on how to avoid the mistakes they made in the past but it’s clear to everybody that they don’t want a singular figure with absolute power. Despite her good intentions, progress is slow and difficult for Leia. It hasn’t been easy for Luke, either. He’s spent years growing in the Force. Despite defeating Darth Vader, he was still raw in his abilities and it took a lot of time to really become a master. Given all of the chaos that came as a result of Jedi and Sith infighting, Force users aren’t received like they once were. Luke is encouraged to stay away from the limelight and has had to taper any ambitions he might have otherwise had of reestablishing a full-on Jedi Order. These conflicts are what have actually given evil a chance to resurface. After decades of planting seeds within the political realm, a faction has managed to seize a strong positioning within the New Republic. Being that we already saw the political angle in the PT, this simply be alluded to within the movie. Palpatine's political storyline from the PTwould help give us an idea of what happened, although it would more so be the dictator/Nazi-Germany version of how evil came to power. This time around, politics in the film could resemble the United States political system (also explains why Leia can't get anything done lol) and the movie would just ask us to imagine how a corrupt group would come to power over a divided republic. (I feel as though this would be an effective way of only lightly touching on the political aspects since I think people see republicans/democrats, whichever they aren't, capable of similar already.) Meanwhile, a Force-based threat, perhaps Plageuis, sees now as the time to resurface. Luke wiped out the rest of the Sith and his small group of disciples are all that is left of the Jedi. With the New Repiblic on the verge of another civil war, there is conflict. External conflict creates internal conflict. Keep in mind that the political/military threat would remain separate, or be an alliance at best. Rather than Palpatine within the Republic, think a political group within the Republic pairing up with the Force user Dooku-Seperatist style... if they had any type of partnership at all. Overall, not only would this help avoid the PT political storyline, it'd promote a feel like the one we had in the original trilogy where Lightsaber fights were just one form of battle. You would have true military conflict (perhaps just seeds of war in the first film) and Force-based standoffs would feel special, once again. It would give Leia (political), Han (military) and Luke (the Force) important roles but we wouldn’t necessary need a lot of screen time from them (remember based on all of the rumors, we won’t be getting much).
