I went in completely unspoiled, and as a result I gasped and whimpered when Han died. I was NOT prepared. I think I figured that if they were to kill him, they'd do it later in the series. Ah, well.
Over/under on whether Ren could ever be redeemed, since he's gone and done the one thing that Luke nearly died to avoid doing in RotJ? Also, Ren probably has a higher body-count to his name than Vader, given the populations on five planets. (Were they all in the same star system? How does that work?) (But then no one never accused JJA of having much understanding of astronomy.)
Man, I loved Rey. For one thing, every time someone showed up to rescue her, she'd already rescued herself. Every friggin' time. It was great.
She called out the stupid thing where the guy drags the girl along by the hand while they're being chased, which has always bothered me--all it does is slow him down, and throw off her balance.
She really is Leia's spiritual heir, in a lot of ways.
That said, why did Luke never train Leia in the Force?
For myself, I really don't want Rey to be a Skywalker or related to any of the old cast. I want her to be just some random kid who was abandoned on Jakku. I'm tired of dynasties.
