Something else I hadn’t mentioned yet was the issue of Luke’s ideology in TLJ. One of the things TLJ got praised for was tying itself back to the prequels by having Luke call out the failings of the prequel-era Jedi Order.
The thing is, there are plenty of legitimate issues to be raised about the prequel Jedi: the fact that they separated Force-sensitive babies from their parents and never let them know their own families; the fact they encouraged an unhealthy level of emotional repression and detachment from the outside world; and the fact that they remained servants of the Republic even as it grew more corrupt and self-serving, going so far as to lead a war against a faction trying to secede.
These are all legit grievances that could’ve been brought up. The problem is, TLJ doesn’t mention any of those. Luke says some stuff about how the Jedi allowed Sidious to destroy them, which means they apparently deserved to be destroyed, for some reason? He says the legacy of the Jedi is failure, despite the fact that the Jedi had been able to keep the Republic together and thriving (for the most part) for thousands of years. And he says that the Force doesn’t belong to the Jedi, which isn’t some groundbreaking statement. Everyone already knew that. The Jedi never claimed that the Force belonged to them.
I get that the point is that Luke is supposed to be wrong, so we can see him have a change of heart at the end. The problem is that Luke’s whole anti-Jedi stance in the first part of the movie is such a flimsy, poorly constructed strawman that there’s no way Luke would have believed it for 6 years. He would have seen through it before then, because of how little sense it makes.
There’s also the fact that Luke, given his unconventional path to knighthood, would definitely not have been the traditionalist, prequel-like Jedi the new canon portrays him as. He would have reformed the Order to correct its flaws, rather than just throwing the whole thing out without trying to change anything. But, I’ll save that for another post.
