Saw it this afternoon... it was great.
My only gripe was Han Solo's clothing looked mint, all the time as if Harrison Ford was going for a photo shoot after each take. But costumes for all others were on point! The guy at the end looked bad-ass!
I found myself feeling some nostalgia. I was lucky enough to see the original Star Wars in theatre (albeit very very young) but having seen every Star Wars in theatre to date, I appreciated this one the most as I was able to fully understand and take in what was going on. As a kid seeing the originals, I just wanted to see Darth Vader and light saber fights heh.
In my opinion, this is the best Star Wars since Ep.4 and 5 (I liked return of the Jedi, but even as a kid in elementary school I thought the Ewoks sucked a little.)
I'll absolutely see it again. Great acting from the new cast; very believable.
