** My own hobby horse is Luke's dilemma throughout RotJ, and his debate with Obi-Wan Kenobi. As originally envisioned, Luke was right and Kenobi was wrong. There was good in his father, and we see that the old man is good at heart when Darth Vader's aged spirit turns out to be a kindly old man. In the revision, Kenobi was right. Anakin Skywalker really had died when he became evil, and thus his redeemed ghost has the aspect of a young, not-yet-corrupted man. I think this is due to the aging auteur shifting his sympathy from the idealistic youth to the cynical senex, but I might be overthinking it. I don't think there's anything in the LOTR EE that really reverses the story told in the theatrical editions like that.

^^^^^^^^^^^^^^^^^^This.
