So, late last night I'm brainstorming possible ways to go with the new Star Wars trilogy now that The Force Awakens is out there and consuming all the box office money as if it were a black hole. Thinking back on what is wrong with the new film, I figure on some way to introduce a means by which those could be fixed.
I accidentally created a viable spin-off series.
It began with the idea that Luke, in the time between Jedi and Awakens made an attempt to resurrect the Jedi Order. He's the only known Jedi, and he's nowhere near the abilities of those who trained him. Neither does he have the resources that the former Order possessed at the time of the Purge. While others survived Order 66 and the Purge, not all of them would survive through to the fall of the Empire and not all would want to rally to Luke thereafter.
This means that there is a noticeable gap in the lore of the Jedi, one that cannot be alleviated by having Leia using her government and society contacts to fund Luke's efforts. No, someone--and it can't be Luke, because he's got students to train--needs to follow up old leads and recover as much Jedi lore and artifacts as can be had. This opens the door to a non-Jedi loremaster and expert being significant to Luke's efforts.
So, we have an Adventurous Scholar sort roaming the galaxy. He explores lost tombs and temples, takes on Imperial remnants and evil cults, deals with solving ancient mysteries and recovering ancient artifacts. In short, we have a way for an Indiana Jones or a Lara Croft sort to become significant. Make it a small group of such figures, one that rotates around as expeditions come and go; the students (and Luke) learn from them about the past of the Order, the Sith, and the Force. Eventually, Luke or others would go along when their talents were necessary.
You see where this goes, right?
Now, one of the big arcs is in putting back together the corpus of the lore on the Force. You do that through critical examination of the history of a thing, and the remnants it left behind (archaeology). This is a big opportunity to take the best parts of the Expanded Universe and bring them back into the canon, address other issues that the films can't handle due to time constraints (like lightsaber construction, or the importance of training), allowing world-building in the space that is otherwise left a void.
And that, folks, is how a creative mind accidentally comes up with a viable series premise while dealing in fan speculation. (Hey, Disney, need another TV series after Rebels?)
