"Someone who never knew about the Force, had never heard used a sword before, used one while anticipating where lasers fired point blank were going to land, and deflects them with pinpoint accuracy three times in a row. While blind. Within a minute or so of his first attempt.
Luke is a farmer. That is off the charts crazy, but we've rolled with it for decades without issue."
Literally every Jedi ever has been able to deflect blaster shots. Given it was what Obi-Wan was teaching him first I'm fairly certain it's a fairly basic skill. My sort of interpretation of how blaster deflection works is that they preconceive where the shot will be and put their lightsaber there to deflect it. If that's how it works, having vision really wouldn't help much.
"Luke pulls off a shot described as "impossible, even with a computer" on his first attempt, after Obi-wan tells him to "use the Force", when it's something he has never done before. But again, we've rolled with it for decades without issue"
That and the "one in a million" lines I don't really buy. We don't know the guy at all. He could just be claiming that because he knew he couldn't do it. There's nothing to prove the guy's expertise on the subject. Same with Han. How could he possibly know the exact chances of hitting the shot? Again landing that shot comes down to anticipation and PM Anakin's pod racing was similar but he had no training at all.
"After how much training? They were in a school."
Luke was being taught by Obi-Wan.
"Not established in the films at all."
It is established better in the Clone Wars, which is also canon.
"Luke learned the only two things Obi-wan taught him instantly. He picked up on what he does in ANH as fast or faster than anything Rey does. This is not really disputable."
The two things he learned aren't very hard at all compared to...
"Rey learned (some) of what Kylo Ren taught her also instantly. There's a tight parallel in their first conscience use of the Force: Rey fails at her first attempt at using the Force (mind trick) twice. Just as Luke fails to block the first few shots fired at him from the training bot. But once they let go a bit, they pull it off.
He just taught her different things. Rey had both more things taught to her, and more cause to try and use them, given her situation."
She out force-pulled Kylo, resisted his mind reading and did it to him, and performed a Jedi mind trick. All of Luke's powers are things we've seen pretty much every Jedi do. Rey's ones we've only seen an elite group of Jedi do.
"Compare Rey's actions to Luke in ANH. What were Luke's failures? At what point was he faced with a test and he failed it?"
Luke was almost killed by some random thugs in the cantina before Obi saved him, gets tricked by R2 into letting him escape, is almost killed by the trash compactot monster, blows up the bridge controls he needs to get across a gap, and almost gets killed by sand people. He spends the whole movie whining and watching everyone else solve all the problems. Even his biggest moment requires him to be bailed out by Han. In most respects he's similar to Finn. They both slip up at times but show potential. With Rey they spend so much time trying to show how she's strong and doesn't need protecting that she solves pretty much every problem that is thrown at the group. There's not much room for her to grow as she's already a more powerful Jedi then 90% of them and that's before she's been trained by Luke.
Both Leia and Ahsoka from the Clone Wars TV series were great examples of complex but powerful female characters. Finn was awesome too as an example of a strong black lead, definitely the highlight of the movie for me. With Rey it feels like they went way overboard with the "empowered woman" trope that they're afraid to show her having any real moments of weakness which makes her a lot less relatable and enjoyable to me.
