I don’t really agree, since Lucas is more than just "a previous storyteller, and I think the creator of this universe has a special place. In other words if major changes are made to the context of his story, I think he should be oke with it.
I value the story’s quality over the hypothetical hurt feelings of one of its previous contributors. I don’t understand the unnecessary complicating of enjoying the story itself by introducing this metatextual and behind-the-scenes drama to the proceedings and then hinging your ability to enjoy what happened to it. There’s no reason for me to put that skin in the game, I don’t get anything extra by doing so.
The second he sold the whole thing for four billion to a completely separate corporate entity, his feelings became a tertiary concern at best. It speaks well to people at Lucasfilm that they’re still involving him, despite prior complications and hurt feelings. But if he’s fine enough with still hanging around and helping when they ask, that should probably be all there is to it from my perspective.
Again: That’s part of why stories are so amazing. Their malleability, their freedom to change shape in order to get across the ideas and feelings of the people telling them. That’s a huge part of why the fan edit community has such an important place here, too. The consideration for other creator’s feelings isn’t taken into account too much, and I don’t know that it should be, because the aim isn’t to make prior creators thrilled or happy, it’s to try and figure out how to make the story work to express the ideas YOU want it to.
