just saw this. lots of thread to catch up on. so, posting first impressions, then going to go back, and laugh at what Im sure others already brought up.
Overall, about what I expected from J.J. Alot of flash, missing substance, or a logical backing, and alot of nostalgia, to the point of almost painful at times..
J.J. doesn't know how big space is. I don't know why he thought it was a good idea to do the Vulcan planet blowing up within visible sight distance to other planets.. which shouldn't even be in the same solar system. AGAIN..
But, even after that, the real issue is totally failing at selling distance and time for travel.
Rebels somehow locate, scan, and ID starkiller planet in minutes. then, declare its charging up and will be ready to fire in 15minutes. And somehow come up with a plan, mount an attack on this planet in another solar system, within 5 minutes, to spend 10 minutes fighting, and Zero travel time. How did the First order even build the thing, if it was that easy to find, and scan?
This totally flys in the face of everything the universe is built on. Stuff can't be this close. Luke's unchartered solar system can't exist if traveling is that easy and fast. Final scene did this as well, without cutting to someplace else, during Rey's trip. No illusion of time. they needed a scene cut elsewhere, or to her on the Falcon doing something, to suggest travel time.
Of course the superweapon draining a sun, and only being able to fire once or something is a bit silly as well... How did it fire the first time, if it consumes the sun?
net bitching about being a mary sue, wasn't as bad as I was expecting. The force persuade out of nowhere was a bit much. how did she even know that was a thing? The resisting Kylo was a bit much, but also easily explained by how big a shit Dark Jedi Kylo ren was. Dude almost lost a lightsaber duel to a stormtrooper.
Leia not having an force training still is a bit silly imho too. This also kindof aligns with the marysue complaints. Rey is inexplicably capable with the force, without training. Why isn't Leia so capable without training?
I do hope the Revan guessing is correct. She inexplicably good, because she was the student that killed the others, despite the claim it was a boy, and got mind wiped for it.
She is show over and over doing things she doesn't know herself how she did it. flying the falcon and that trick somersault, to give Finn a clear shot. This could be explained with the force in general.. But does really seem like a Chekhov's gun. But at the same time.. J.J. is rarely that subtle or patient..
