So I finally got time to go and see it. I think I must be the only person on the planet who hadn't seen it - I was literally alone in the theatre.
I liked that it had characterisation, dialogue, good acting and chemistry, all notably lacking from the prequel trilogy. I thought the opening with the Star Destroyer eclipsing the planet was pretty much perfect - a call back to A New Hope while being completely new. Shame the rest of the plot was more or less what we'd seen before. Starkiller Base was a nice touch - Luke is called Luke Starkiller in early drafts of A New Hope. The Imperials generally have brains - even the Stormtroopers act like competent soldiers, reacting rapidly and sensibly to the warning of incoming X-wings. They still can't hit the broad side of a barn, though, where the heroes miss maybe three shots in the whole film.
To add to the "who is Rey" debate - did anyone else note that "when you're desperately trying to sleep at night, the place you go, the ocean and the island" (or something like that) that Kylo Ren forces (hah, see what I did there?) out of Rey is a dead on description of the place she finally meets Luke? Regarding her skills with the Force - she picks
everything up quickly when she's around someone who knows what they're about. Her assessment of the problems with the Falcon
exactly matches Han's to the point that she completes his sentences. She understands Chewie, BB8, and Teedo, plus Basic/English - that's four languages. She picks up on what Kylo Ren is doing to her when he tries to mind-rape the map out of her, and then uses that on him and the guard, but uses no other Force skills until Kylo Ren tries to Force pull her lightsaber to him - whereupon she learns that trick. Then she's in a lightsaber duel with a (semi-)trained opponent. Whereupon she's suddenly at his level (though he's off his game after murdering his dad and being shot by Chewie's bowcaster). I think she picks things up directly from people around her.
Things I didn't like. Why did the Captain with the cool armour just turn off the shields for them? The Stormtroopers generally seem to be supposed to be "death first!" kind of people. And why does a captain of infantry even know how to turn off the shields, let alone have the authority to do it? Kylo Ren became whiny and annoying when he took of his mask - kind of like a
teenage Snape. JJ Abrams still clearly has no concept of scale. Somehow the final attack on Starkiller Base was not as gripping as the trench run from A New Hope. I think there's something about the way the old one is filmed - cutting between the action and watching helplessly from Yavin IV, Leia's reaction when she thinks Luke's been killed early on, and the graphic of the moon slowly appearing from behind the gas giant.
