I took the kids to see it tonight. My 9 year old daughter loved it. She had no idea. We sort of tricked her into thinking we were seeing the Peanuts movie again. It blew her mind. My sons are a bit too young to get it. But they watched about half before they got bored. My wife took them out for a bathroom break, and to let them run around a bit. Then, they came back for the rest.
I will say I enjoyed it more the second time, although I still feel they were a bit lazy. Also, there were a couple things I hadn't noticed before that I picked up this time around. I'm off to google next, but I think I saw Snoop Diggity Dogg in the bar scene.
Now, if you haven't seen the movie, don't read this next part. These aren't spoilers, but they're a couple points that I think I've figured out.
First off, it seems like they're beating us over the head to think that Rey is Luke's daughter. I think that's intentional misdirection. I think she's a Kenobi somehow. If you want to discuss why, we can talk about it. Also, I think Finn is a Calrissian. Don't tell me a smooth operator like Lando doesn't have a ton of kids out there.
