At first I didn’t understand why TLJ left so little story threads for future entries, feeling more like the final act of a story, than the middle one. In the context of what I wrote above it makes perfect sense. Future Star Wars movies won’t have these connective tissues like in the past, because it prevents the general audience from connecting with it, or worse even go and see it, since they need to have seen the previous entries to fully appreciate the new film. TLJ has eliminated that problem.
TLJ is the penultimate story if the Saga. It had to tie up a lot so that 9 could complete things. I can see how it was aiming to do that. Your theory about it resetting/rebooting things would make sense if they were going to continue the story, but with news that RJ will be doing an unconnected trilogy, it makes no sense. You have argued above that we need to know the filmmaker’s intent an RJ is a huge Star Wars fan so I don’t see how that equals deconstructing what came before. If the correct interpretation must incorporate the original intent, then you are quite mistaken in your deconstruction/reboot theory.
