I would say the end is quite bittersweet. Anakin was redeemed but Luke lost his father, Leia the woman who Luke had deep feelings for ended up being his sister. And he all alone is supposed to revive the Jedi Order, despite losing both of his teachers Obi Wan and Yoda. And having no idea what he is supposed to do other than to train Leia as instructed by Yoda. Pass on What you have learned.

Since we know Luke fell to hubris just like Obi Wan and continued the cycle. I don’t see a happy teddy bear picnic ending to the Saga. I’ve seen the Disney trilogy. I know what happens next.
