I actually thought The Last Jedi gave us a really nice, naturalistic, presentation of the Force, and went a long way to retcon the mistake of Midichlorians, blood tests, and ‘all in the genes’ exclusivity that the PT advanced.
Rey isn’t a Skywalker, she isn’t a Kenobi. She’s no one. And for the audience, that makes her everyone.
I agree with this. RJ (and JJ in TFA) made the force magical again, and personally I’m not fussed by Rey not being a Skywalker or a Kenobi or whatever, I think ‘anybody can access the Force’ is a far better take on it.
