You can label Disney's sequels as many things but consistency, quality and forward-planning are not among them. The only legacy of the sequels is a tug-of-war between J. J. Abrams and Rian Johnson, with each film contradicting the last. All the while presided over by an absentee Star Wars writers group, more content to stand in front of the cameras at press junkets then actually steward the franchise Disney put then in charge of. That's how the EU outsells this dumpster fire of a sequel universe and why Heir to the Empire will always be the true successor to George Lucas' vision.
