I've pretty much re-run the entire grip field today... even though I've done this several times before... so if you just read all my responses from today all your questions will be answered regarding the "stuff like that" you're referring to. I fielded this particular question earlier as well & copied it here. I think it's very understandable.
You in a way made our points for us, in the gripes a lot of us have.
At no point in the Movie did it tell us that Rey learned all that shit when she was inside Kylo’s mind.
That’s the whole point isn’t it? The Novelization was written later to help fill in the gaps and holes, that a lot of people didn’t like about the movie.
So while we are arguing about things we do not like about the movie, bringing up the later supporting documentation does not help us like the holes we see in the movie itself.
On your points about Rian and JJ and the story, I’ve watched many interviews with Daisy’s, JJ and Rian all talking about these things and Hamill some as well but most of his are just salty from being pissed on.
A little bit later when I can get on my PC instead of my phone I’ll revisit this and put together for you what I have seen, and also rewatch and reread it myself(since it has been some time) and we can discuss from there.
Just posting tid bits now I don’t think would put it together correctly.
As far as the Jedi order stuff I’m sure they had that in mind, it’s been the direction I think they’ve been moving with as shown from some episodes in Rebels and clone wars.
That I’m sure was there, no snoke backstory, no parents for Rey and no reason to have visions and the light saber calling her I think were not.
And probubaly not luke sucking sea cow tits either. Etc.
