Saw Rogue One.
This actually reminds me of some years back when Lucas wanted to do that tv series in parallel with the movies. Have the movies be the grand space opera fantasy adventure side of the good vs evil, but do episodic tv that showed the "underbelly" of the SW universe in self-contained stories to expand background and potentially appeal more to the adults then the kids.
The SW 7, 8, 9 etc being Disney's grand fantasies and the one-off films being the grimy elements that go on in the background.
On another note, I liked the way they tried to use cgi characters to have that connection... But I think they overused Tarkin, and while that end note of the film made it a nice "this is 5 minutes before SW IV: A New Hope" announcement I think it would have worked better as a side shot rather than a full blown full facial close-up.
