I just got back from watching TFA for the third time. In case you haven’t guessed, I’m firmly in the ‘love it’ camp.
Upon multiple viewings, my girlfriend and I (she’s seen it twice) both got the impression that Han Solo and Kylo Ren might know who Rey is (or at least suspect who she is). That might also explain why Leia hugs Rey the first time they meet (although ignoring Chewie is still inforgiveable!).
As a side note, this time I saw it on a non-digital screen in a crappy old local cinema and it helped it feel a bit closer visually to the Original Trilogy. If you plan on seeing it multiple times I suggest mixing it up - So far I’ve seen it in IMAX 3D, digital 2D and non-digital crappy 2D. Each time was different (but all great).
