With regard to the Marcia Lucas thing, I’d say that no-one actually ‘gets’ Star Wars and that includes its creator. Lucas was famously ‘30% happy’ with the first film while we as fans were an obvious 100%. So arguably from the beginning Lucas himself didn’t get it. I’m not saying this to diss George, I’m just saying the whole thing is deeply subjective. I myself think Gary Kurtz is the one who ‘got’ it - but his vision for RoTJ and beyond rankles a lot of people.
Back to the ST, while I have my issues with TLJ I think Luke’s death (and the manner of his death) was one of the greatest moments in the saga.
