Didn't like it. I'm not sure I can lay a finger on it as of yet. Some are just really minor details that end up irritating me (C3-PO's dub, stopping laser beams). Others I better not dive into as it would start to put into question pretty much all of Star Wars (we are family *sings*).
To pick up some things though:
Yes, there was a lack of Jedi order in this movie, but it isn't for want of trying. It's actually the very story of the movie at hand that little emo-boy popped the party and uncle Luke felt so guilty he had to hide somewhere, leaving clues with an old man, and curiously the other part in R2-D2 and the imperial archives? Anyway, Jedi order - I'm really happy about that tbh, this way it's ambigous with every force character we see. Having hundreds of little Jedi roaming around would be a too imbalanced force yet again.
Stormtroopers finally getting some recognition was fine. Even that one guy with the baton was awesome. The lightsaber resistant baton itself... eh. But then we have the shiny commander lookig all badass and her role amounts to... nothing. They didn't need her for the identification of FN2387 since Kylo later made that connection to the trooper on the ground (plus point for knowing all his minions). And later she was turning down the shields without putting up much of a fight or adding anything, consequently she's gone just as fast. Actually her role is that of droid. Accessing a terminal.
The comedy... oh the comedy. How often the audience laughed. And yet it felt so forced how each of the characters got some witty comment here or there to lighten up the mood. Might be a sign of the time we live in more than anything, but I could do with less of that.
Which brings me to one other point, the age of the cast/characters. Previously, we had generals/admirals/whateverals being seasoned men presumably with battle experience. This time, most of the staff running THE most powerful snowball in the SW galaxy are... just out of university? If not Highschool. Maybe I just didn't see it, but other than Snoke no one looked like they could have had any experience from the time of the empire. Either way, fitting environment for teenage, angsty, disney comedy.
I guess Starkiller itself being implausible, if not just for the stage of the last fight as the atmosphere wouldn't survive the sun-sucking, has been chewed through enough.
So, prediction time: I don't think Rey is related to anyone (*hopes*), but she could have been part of Luke's first try to set up an order and then hidden away on Jakku. Or whoever brought her there was too late, yet didn't want to keep her. Kylo naturally survived, because finding people on a planet/base turning into a sun is easy and he will totally finish his training of... Ren? Which means we have both sides beafing up, question is though on-screen, or off-screen. The easy and obvious solution of a force baby between the two to end all this will hopefully be passed on.
Before anyone asks, it's still a good movie that manages to pick up the legacy, spin it in its own way and deliver some hours of fun. The music and effects are great, the pictures fantastic even.
