The idea that Luke Skywalker became a depressive old hermit who checked out for a decade because he was so ashamed of himself and angry at losing touch with what made him “a legend” in the first place? That’s not blasphemy to me. That’s interesting. And the way it was done was not just sad, but charming, too. To a lesser extent, a similar thing was done with Thor in Endgame. And to a lesser extent, some of his fans reacted much the same as Luke’s fans have reacted: The decision to do it was, in and of itself, unforgiveable, and so anything built upon that (to them) broken foundation isn’t worth giving over to. All they see is the humiliation and the “disrespect” to such a strong character. They see that as a punitive act against their hero, and they basically just… stop there.

I don’t entirely agree this is the case. To some sure, but to many others the disrespect is not in the humiliation, or punitive act against the hero, it is in the fact that they feel, it has not been properly motivated or set up. To them it’s like the story telling them, Luke’s different now, deal with it, and if you can’t, that’s your problem. For me it is similar to having the PT end with Anakin the hero, and then introduce him as Darth Vader in the next movie, and then show a tiny ambiguous flashback to explain how Anakin is suddenly an evil mass murderer.
