Just saw it. Not a bad movie, if a bit disjointed. Regarding Rey vs. Kylo Ren, I actually feel this had worked, though obvious chosen one is obvious.

It might have been better if her "destiny" was a bit less hamfisted. That said, apart from the first scene, I got a feeling that Kylo Ren was actually a very crappy "Dark Jedi". He wasn't well trained at all, he just thought he was. Aside from the scene with the blaster bolt, he's not seen doing
anything that would hint he's anywhere near OT Jedi. Indeed, quite the opposite, and it's shown he knows it. Kylo Ren was not a proper Dark Jedi. He was a very angry wannabe who had some basic training, nothing more. Notice how he's tearing up everything around him, wasting his energy on trashing his own base. Vader, on the other hand, was the epitome of tranquil fury, killing people for failure, but otherwise showing emotion only in extreme situations, or to use the Dark Side powers. When we see experienced Dark Jedi (Dooku, Vader, Palpatine), they're quite collected, saving their fury for the times they use their powers. It is
very clear that Kylo Ren has barely any control over himself, thus probably preventing him from being a truly effective darksider, as opposed to pulling an odd telekinetic trick when he's still reasonably collected. I'd expect anyone with actual experience, force powers and fencing experience to be able to wipe the floor with Rey, despite her quaterstaff training.
As for what Millennium Falcon did, I think it was actually quite well done. Both exiting the hangar directly into hyperspace and going through the shield are treated like utterly crazy things to do. From what it looked like, they might have actually started to exit right outside the atmosphere (maybe even outside the shield, given that he said they were going to go through
at lightspeed) and got into it during the deceleration phase. Remember, Earth's atmosphere is pretty thin at 100km already and 400km is high enough for ISS to fly. In space terms, 100km isn't a lot, and they definitely were going straight down. Of course, that's exactly why it was such a risky maneuver, but come on, it's
friggin' Han Solo. Probably the only pilot good enough to pull this of
and the only one mad enough to even think about trying it. The in-universe reaction among the pilot community would've probably been similar as on this forum.

I just hope nobody thinks to make it a regularly used trick later on.
Other than that, ANH rehashed. Lazy plot, but "The Hidden Fortress" is not a story that gets boring after being told once. I liked the new characters and especially the new stormtroopers. The TIE fighters were a bit odd (dunno what was the big idea behind having a
gunner in one of those dinky things), but I suppose it did work out. Seeing one of them piloted by the main characters was a welcome change. They also did a better job of making First Order look like an Evil Empire, something which the Galactic Empire didn't really convey all that well. You could actually root for the Empire (Vader and Tarkin could be pretty much directly blamed on the evil stuff we see it do), but I'd imagine the Order isn't going to have quite as many fans.
One thing I'm hoping they'll do in ep. 8 would be giving Rey a double-bladed lightsaber. Going to it from the quaterstaff (which with she's quite handy already) seems like a logical transition. For some reason, I just "see" her using this kind of weapon.
