A thing that felt maybe wrong about coming back was the fact that the original trilogy had a beginning, a middle and an end. But there's two ways of looking at that, on the one hand, it had closure. But if you look at it another way, it's the story of how Luke went from becoming a farm boy to a Jedi and then the story ends. It would be like telling the story of how James Bond got his license to kill and became 007, and the story ends.
