I don't get it either, waited all your life to see what happens after Vader dies? there were lots of material depictng just that before it was retconned, plus the fun you could have speculating shit, or just leaving it at a warm feel it was already over.
I would have preferred we got an new star wars trilogy every 30 years, not the yearly movie we are gonna have now, it would be like poetry, it would rhyme.
