He only fucked up 1/3 of it.

That math doesn't math. He was directly responsible for 2/3s of it, and the other third he plowed over.

Rian's script was a genuinely excellent anarchist critique of space opera. Whether or not that belongs in a numbered Star Wars movie is debatable. But the real disconnect with the audience is the edit. The film we got is not excellent. The film we got is not exactly good. And yet - all popular criticism is this same irrelevant fluff.

Luke being a hermit was JJ's fault. It was immutable, when Rian began. Rian's explanation was fine. Jesus Christ, his description of the Force is incredible. People keep shitting on his opinion of the Jedi as if the Jedi way didn't fail the Republic, fail his parents, and fail his mentors, all two of whom kept playing mind games even after death. Some girl shows up expecting How To Hero 101 and of course he says no.

I ask you - as opposed to what?

Sketch it out for me. What does Luke's motivation look like, when a Force-sensitive rando shows up on his extremely private retreat, offering a tool he built from scratch and obviously abandoned? The man knows smugglers, bounty hunters, militants, and diplomats. He's attuned to a psychic power that permeates all life and matter. Some glorified barkeep having his backup glowstick in her basement would not stop him from getting it, if he set aside a month and gave half a shit. Tell me what it would look like, if it looked like that Luke Skywalker was well-written, in your eyes.

Me, personally? I'm quite happy with him kicking Rey straight down the only-what-you-take-with-you hole. He doesn't toy with her except to show her she doesn't need training and shouldn't want training. Yoda played some Mister Miyagi shit while he was looking for a level-up before 1v1-ing the scariest motherfucker in the universe. "Ben" was a dutch uncle his whole life and never mentioned he had space-wizard bona fides, nevermind that his dad was alive and well and the scariest motherfucker in the universe. Jedi hermit Luke points out: the fact this trilogy exists means that what Luke did did not work. Of course he tells her not to repeat his mistakes. His ambition did not solve the problem.
