Don’t love it. But I really, really, really like it. I won’t go into detail, because everything I could say has been said before and better.

I think a lot of questions that came up with this movie will be answered in the next one. Rey’s vision for example. The first thing that happens when she touches the lightsaber is, she finds herself in the Cloud City corridor where Luke and Vader duel when Luke reenters the building after being thrown out of the window. It isn’t her past or her future, or is it? Is she Lukes offspring?
