That's where you're not getting it, or the story, or the entire theme of Star Wars in general. She is the new Luke, period.
The female character lead in Star Wars seems to be a hard pill for a lot of fanboys to swallow. Boo. Hoo.
Lead female roles, like Rey, are a welcome breath of fresh air. The time for all-male leads is done. It's DONE. So, it only makes sense that if you have a character like Rey, that she is not going down a path where she will not be an inspiring character for young women. How is that so hard to comprehend? And if you don't want or welcome this....maybe new Star Wars (or sci-fi movies anywhere) are not for you.
I for one am tired of reading post after post about women in lead roles that are slammed to death, picked apart, nitpicked from every angle... that just screams misogynist rhetoric.
Rey is bad ass, she is here to stay (thank f-ing god) so some of you will need to deal with it.
