As for Rey’s powers it seems to me that RJ has simply changed the nature of the Force for his own convenience. The OT (and even the midichlorian-infested PT) establishes the Force as something that requires serious training and incredible mental/emotional discipline - irrespective of the wielders’ natural proclivities. In RJ’s SW universe the Force manifests like X-Men powers (see ‘Broom Boy’).

I’ll correct you here as that would be JJ Abrams. And as I’ve said, she can pick up powers, but has no guidance as to how to use them. Luke had serious doubts. Ben and Yoda had to overcome his doubts. That is one of my biggest problems with the complaints about TLJ. So much of what Rian did was based directly on JJ’s setup. Blaming these things on Rian is nonsense. Luke’s self exile after Kylo turned and destroyed the school, Rey’s ability to pick up powers as soon as she sees them, the First Order being like the Empire, the Resistance being like the Rebellion, all these things come straight from TFA and Abrams.
