I disagree Dre, the movie shows several moments where Rey is associated with the dark side and even moments where Kylo is with the light. It also goes deeper into nuance by having the mentor figure grapple also with his past failure and his present opportunity.
It is all there on screen and in the script, for those who choose to be selective and not accept it because it doesn’t fit into your ‘head canon’… well no one can do anything about that other than themselves.
