ok, way late to the party - finally saw it yesterday, finally read through the first ~15 pages of this thread... agree with most general opinions of the movie. I thought it was really well done, especially in comparison to the prequels, and I think there was enough new interaction and storyline that it was a fine stand-alone movie for someone who's never seen any of the other movies (which I know, because J came w/ me and he's never seen any of them.... shocking, but beside the point).
I liked how they reintroduced the Millennium Falcon - "it's a piece of garbage! ...garbage will do!" - which definitely makes you think of Leia, but then there are too many parallels between Luke and Rey for me to think that Rey is another kid of Han/Leia. There was not nearly enough recognition between Leia and Rey for that to be a maternal bond, and I think Leia's role typically has a softer side for those types of relationships. I think Han did the double-take/asked her name because he does know who she is/who her parents are, but I don't think he's her dad. I think she's either Luke's kid or somehow a descendant of Obi Wan. Leaning towards Luke, though, just based on all of the parallels/use of his theme in her scenes.
Great chemistry between Finn and Poe, and Finn and Rey. As others have said, I look forward to seeing them act together going forward.
Random - I really appreciated when Han blasted the doors open by just shooting the control panel; pretty much exactly what he did in RoTJ, and they panned to his face, which was kind of a "yep, still works!" expression. Made me smile.
Also, Kylo Ren is totally Ben (after Ben Kenobi) - anyone who even questions that, just don't think so hard.
...i think that's it.
