That's really interesting. I do think, out of the gate, that Daisy Ridley sells the acting of "how the hell did I just do that?" in addition to things like "wait these things are real?" and awe and shock, in all three films, when she sees some of the OP things that even she finds herself doing.
I've been on a thought experiment lately thinking about role reversals in the Sequel Trilogy - I think Ben Solo is kind of the "natural protagonist" and hero but I think there's real value to having him, and the son of Leia & Han, be the bad guy and the whole flip dynamic being a thing to explore the nature of why somebody is "good" or "bad" in the Force and in these stories. But even in the inverse, Rey almost feels like she has the Villain's Journey in structure. The Gifted Natural, but is she "hopeful" (her parents are coming back for her, just you watch) or "delusional"? She meets Luke and goes right to the Dark. She's Nobody. No wait she's Somebody. Somebody Big. She's been lied to. She's scorned. The Gifted Natural. It all comes so Quickly. Seductively. Almost like she's been using the Dark Side the whole time, whereas for Kylo, ironically the Dark Side comes very, very difficult. It's not easy for him to do bad things.
They meet somewhere in the middle, but her path, her journey, her story structure, seems tailor made for having had the Dark Turn actually happen. So I do tend to agree that the Sequel Trilogy would have been stronger by far if they'd crossed paths in the middle and her O-P Rapid Growth turned out to be as much of a Problem or Hindrance as a Solution. You want to give your characters real emotional hurdles to overcome and they certainly made some interesting attempts to do that with Rey, but really if she's going to have Fast-Awakening extreme levels of skill and power, that same skill and power should be the Very Thing that's a problem to overcome. Not Kylo and a parade of Wizards of Oz behind increasing amounts of Curtains.
(on that aside, Ben should have absolutely been a Jedi Vice Cop undercover and having to do Terrible things to discover the truth that Palpatine's Wraith was behind everything. His balance of guilt and torment versus the greater good would be brutal ... and make her go dark even as Ben came back to the light and they traded. And then it's almost like The Departed in Star Wars.)
