Oh, and Finn's skill with a lightsaber out of nowhere. When it's been said, time and again, I'm fairly sure, in canon, that it's damn hard to learn how to use a lightsaber without chopping off a limb. Rei's skill too, for that matter, though obviously the Force guides her.
Yes, because Luke Skywalker took more than being introduced to the force to start deflecting shots blindfolded and sending a missile down a tube that goes halfway through a moon.
And Anakin Skywalker took more than being around Jedi for a few days to use a starfighter to destroy a large battleship using the force without any actual pilot training whatsoever.
Rey's expertise is exactly in line with the other movies.
Luke was being trained by Obi Wan; that was not in the middle of a firefight as your choice of words would give the impression of. And even then, it took him a bit, at minimum a few days as far as I'm aware of the timeline working, that's literally just being guided by the force, and learning to be guided by it. Likewise, he had already learned to use an X-wing. That was just the force guiding his shot.
Anakin was in the prequels, guided by Force Fate Edition, something something podracer, and it still showed him bumbling about. (it's been a while since I've seen Phantom Menace, but I also don't remember it being specifically the force).
The others bumble into success; it's improved luck and first steps; they're learning and their potential is being shown. Rei doesn't even get introduced to a Jedi. Resisting mindrape, that's cool and fine and all and I thought if they'd left it at that it would be pretty cool and the same level. Instead, she manages to counter-mindrape, is intrinsically infused with the Light Side and from what I can tell was implied can't use anything but the Light Side, given all the emphasis on her 'cool down, meditate' stuff(her just sorta automatically realizing 'this is how I should do this' is another matter that I get annoyed at), gives a dude a force suggestion on her second try(might be misremembering but I thought a fair part of the point of Obi-Wan doing it was to show that he was old and skilled in the ways of the Jedi)...
She's not even a whiny teenager like Luke was! Her only apparent character flaw was the attachment to her parents, and that appears to have been resolved! Maybe I'm misremembering one movie or another, but if so, please remind me, as it should help me feel better about the franchise half my childhood was spent watching. (obviously the other half was LotR)
