Yeah, I see that too, I just think it’s symptomatic of an unwieldy/messy script more than it is intentional malice or whatever for the series. That’s ridiculous to me, it’s at worst a guy who has different ideas [than you or someone else] about how this all works and who these characters are.
The most charitable interpretation I can come up with is Rian Johnson was going for something along the lines of a “Wizard of Oz” type message, where it turns out the Scarecrow and Cowardly Lion had all the brains or courage they needed all along, and just needed to believe in themselves to access it. Something like that. That is sort of compatible with what happens with Rey’s journey of self-discovery, where she sort of self-learns the Force. There’s nothing inherently wrong with a message like that, but it’s not a fit for Star Wars and what was established before, where the Force requires a mentor to learn and is already part of a pre-packaged, venerated mythology.
As for “intentional malice” - I’m not really sure what that would even mean in this case. I don’t believe that like, Rian Johnson sat down one day and started angrily writing the script, saying things like “I’ll show those stupid Star Wars fans… they want to see Luke do they? Oh I’ll give them Luke… I’ll give them Luke all right!!! Bwahaahaahaaa!!!1!!! *starts choking on iced latte*”
I think Rian Johnson just wanted to take Star Wars in a new direction he thought would be interesting, while avoiding accusations of just retreading Empire Strikes Back and working within the story parameters that carried over from Force Awakens, and he ended up writing a very misguided script. At the very least, I found it heartbreaking watching the Mark Hamill interviews about this.
