I’ve never really understood franchises being exclusive to one author, but in Star Wars’s case specifically, because it’s a film series (and not, say a book series where there really is only one author), Lucas has never been the only creative mind behind the series. The world of SW has been created by a variety of people from the very start. Feels disingenuous to ignore that collaborative aspect - which is to say nothing of the series’s patchwork/pastiche nature, which in my mind seems to invite baton passing since the series is more about assimilating past stories to create a modern mythological adventure, rather than the holy “saga” that Lucas later tried to make it into. There’s this sandbox where it would be silly to limit it to just one guy playing in it. Now, when it comes to the “Skywalker saga” as LFL has reframed the episodes, even then there’s a meta resonance to having the next generation round out the story that Lucas began.
