I can feel them trying to push Rey in that direction, but I would be so much happier if she was just a random, unrelated person. Yes, the entire series has so far been based around the Skywalkers. So that’s what makes it even more heartbreaking to Luke, Leia and Han (and also the audience) that the Skywalker who should be leading this generation into a new trilogy, Ben, has been seduced by the Dark Side. I think having Rey also be a Skywalker detracts from the tragedy of the family losing Ben. I’d much prefer the idea that they found this scavenger on some random planet who can rise to become the hero that Ben Skywalker-Organa-Solo refused to become.
