I liked it but in many ways the film felt hamstrung by being made by a Star Wars fan.
Certain things just seem inconsistent with what we know from the original films and because there's not much rhyme or reason, come across as simple imitations of the themes and actors from the original films:
The First Order are just Empire 2.0, there's no explanation for who they are or what their motivations are, the extent of their powers or why they're still around after the Emperor was defeated.
The New Republic is some extras in Coruscant. Why, if the Empire was defeated, is the New Republic not the official opposition of the First Order? The name "Resistance" also implies an underground movement against an occupying force, but the actual balance of power is never addressed. The Resistance, despite being on the winning side of history, are scrappy underdogs with rag tag equipment again, just because. Their base is overgrown again, just like it was on Yavin, remember that guys?
With this lack of world building, it feels so uninspired, just retreading old tropes for the sake of familiarity. This is actually something the film did worse than the prequels.
Of course there's another planet destroying super weapon but somehow it's barely of any consequence that billions of people just got murdered when they destroy Coruscant.
It annoys me how proficient Rey is with the force with zero training.
It annoys me how lazy the infiltration of Starkiller Base was. The shields were lowered because we bumped into Captain Phasma, who just complies when asked at gunpoint without any resistance and is dispatched offscreen with another reference to ANH. This, despite Phasma being presented as a powerful, merciless figure who fully subscribes to whatever the ideology the First Order has. If Phasma does't return it strikes me as such a waste of good character design.
Speaking of character design, Snoke sucks and we shouldn't have seen him. The film showed its hand too early with Kylo as well, we should have seen his face first when he encounters Han.
Lastly, what the hell was going on with that last shot before the credits, The one thing all the films managed to do, even the prequels, was establish lasting final shots before the credits. The last show in TFA was just weird, it looked like something out of a TV movie, spinning aerial shot of an inadequately staged area. Fuck.
I did actually like the movie, BB 8 stole the show for me, but god damn ther more I think about it the more things I find wrong with it.
