I think I like this kind of treatment of the Force much better though.
It falls in line a lot more with the fairytale superpower that stems from belief and inner peace than midiclorian-driven shaolin monk cult bullshit ever did. Like, I know it's gonna be hard to fight against that image firmly implanted in fans' minds by the prequels and the EU, but from a narrative standpoint, a protagonist being pure of heart and coming from a line of powerful Force users is a great device. Luke didn't take all that much time to be trained either, the Force shouldn't really be about "I trained 20 more years than you did and now I am much more stronger!"
It'd be interesting if over the course of the following films they could twist her innate talents somehow, make it into a temptation, there's a lot of potential for Rey to grow as a character, and she's not too bad at the moment either since she doesn't really want anything to do with the new role being thrust upon her.
