I just think having Rey’s power being tied to a male bloodline feels so lazy and totally defeats her purpose in my eyes. And regardless if you feel she needs to be related to someone, I think cramming all that information into the last movie was a mistake. If they wanted her to be Rey Palpatine, they should’ve told Rian that’s the direction they want to go in. But once his movie was out and she wasn’t, Abrams should’ve continued painting that picture rather than trying paint over what was already on the canvas.
I fully believe that she was a nobody when they made TFA, and JJ only made her a Palptine for the sake of TROS.
