I get that it's hard to make cg characters look real, but every time a cg character was on screen it completely took me out of the film. Really wish that animatronics and physical makeup were used instead. I'd like to know why Snoke, a very human design, is built by CG instead of physical creation.
It was definitely a JJ Abrams joint. No sense of wonder and the film could've used an extra hour+ so everything doesn't seem so rushed. Finn went from stormtrooper to being a key member destroying the new death star in a quick minute. I'm sure they'll explain this away with 'oh he's in tune with the force', as with all Star Wars writing problems. That explanation is fine, but loses meaning when you throw it around willy-nilly
When I can glance at the platform at the beginning of the Han & Ren sequence and immediately know what is going to happen, and then you use idiotic dialogue like "I know what I have to do, but I'm not sure I'm strong enough to do it", how exactly are you not going to know that Han is dead? The characters having a front-row seat, too. All of the plot was telegraphed, nothing was surprising.
The Guardian's of the Galaxy influence ruined any tension, too. I don't like Finn cheering on the work of a pilot in the middle of a warzone. A good green character doesn't even notice what's happening in the sky when there is fire all around them and they're in danger. This dude was in shock seeing his first combat action, now he's suddenly stoically joking around on the battlefield. A lot of the humor (even though it was fairly funny) stopped all of the dread. Han & Chewy, yeah, they've been in enough shit to be able to joke about it. Rey was entirely believable, though. She was in some shit and she acted like she was in some shit.
When Abrams's last two films are glorified remakes, and he is still applauded for them, it may just be that modern blockbusters have, finally, completely lost me.
That said, Finn is the best lead Star Wars has ever had and every time he wasn't in a scene, I wanted to be in that scene.
Edit: I may be looking at the film to much as a film, and not enough as a Star Wars film.
