I just came back from my second viewing, and it's true, all of it... Movie's even better the second time. I paid close attention to the Kylo/Rey fight, because there's the never-ending power level discussion... It's just so obvious that Rey is fighting a highly weakened Kylo Ren. Not only did he take that bowcaster shot, but Finn also manages to hit him once with the saber, and he looks very unhinged in general (just having killed your father could add to that). There are a couple of close-ups to the blood trail, so it's pretty obvious they're telling us he's pretty weak at that point.
Also missed some stuff the first viewing: only noticed the huge scar Rey gave him now. Ren also got Finn good, that was a nasty cut across his back.
Have to agree with all the people thinking Ren is an interesting character and villain. He does nothing but fail in this movie and that's what makes him intruiging. The fact that he's an angsty teen now, will only make his overall arc more interesting, because we'll probably see a very different character in later episodes. Ren is like the 'slow burn' character of the movie: the more you think about him, the more interesting he gets.
