I dont get this not-wanting-rey-to-be-a-skywalker thing. the films have always been about skywalkers. like, literally all of them. there hasn't been one not about a skywalker.
I'm fine with it so long as it's handled well. Rey should be pissed at Luke for him leaving her on Jakku, Luke should feel a mix of relief and also grief over her being okay but also of her pursing the use of the force that will instantly make her a target of the first order and, of course, the shame of not being there for her.
It can be done perfectly fine, in a manner that works. Given the mountain of evidence piling up regarding Rey's link to Luke, y'all are just setting yourselves up for disappointment if you think she isn't a skywalker.
