I recently re-watched 6 and 7. I kept an eye towards 8. Even in 6 as old as it is there is the foreshadowing we see in 7 and probably 8. I was surprised at some of the continuity. I have gotten over some of the rehashed themes from 4 that found its way into 7. It allowed me to enjoy it more a second time. They just weren't necessary and for older fans an annoying distraction. Even the title for 8 comes from a Yoda deathbed quote. One could take the title to mean that the Jedi are at an end, a transference from Luke to Rey of the title or that it merely refers to Luke.
