Disney has its moneymaker. The Daring Genesis of J.J. Abrams’s Star Wars: The Force Awakens (via The Atlantic) -- Lucas wanted to make the equivalent of Hunger Games, rather than Star Wars (A New Hope)?
Another opportunity for schadenfreude.
If Rey seems incredible because she is skilled at everything despite being abandoned on a planet (to herself?), maybe it's because she's a Mary Sue character for the script writer?
