A critical as I am of George Lucas he might have a point, and Mark Hamill had a point. The Saga has a beginning, a middle and an end. The original is about Luke. The prequel is about the downfall of Anakin Skywalker, as poorly as it was done, regardless. that was Lucas intention. Unless you do a sequel where you have a period of rebuilding and democracy restored, I don’t see a point.
I think things like this also became an issue for the ST, from a character perspective, when TLJ confirmed that Rey was a nobody. Yes, on paper I think there’s really not much wrong with the idea and I think there’s plenty of engaging story and character work to cover with Rey using that (that I think TLJ does almost none of basically, I think mostly using it mostly to pull a ‘gotcha’ and meaningless to me attempt at some kind of oooh ahhh idea). The issue is, I think, that by making Rey a nobody, Rey has no legitimate personal stake in the main story of Star Wars and it’s central characters, beyond being an observer, like she’s an audience member, a fan.
I think it’s not out of the question that RJ may have perceived this as well and rather than use that to try and work her in (if that would have been given an okay by Lucasfilm), RJ just sits her down and has her react to the family soap opera stuff, and maybe RJ decided to use reylo to try and coerce Rey to be involved in it all.
