ChekovSulu would be on the edge of his seat for this one. It's a hard film to discuss without massive bless'ed spoilers. Like when Chekov *Gasp* or when Sulu [REDACTED] Seriously, I'm having trouble thinking of things to say that AREN'T major spoilers. Bones gets like, five or six of them on his own!
The film goes out of it's way to tell you that NO ONE is safe, but it does not do so in a cliched "Main character gets shot through the head" way.
I will say this, my worries about the female science officer being a damsel in distress were dismissed, she fought as best she could, and ANYONE would scream from a kick like she takes.
The visuals were once again striking, and they majorly cut abrams lens filter budget.
One thing I do need to say that may be a spoiler to some is that the fighting is BRUTAL. No clean antiseptic camera shakes like on the television series. That being said, no one is killed by a randomly exploding bridge console. My guess is that this incarnation of Starfleet invested in surge protectors.
One thing they brought up but was never resolved or commented on, something was medically wrong with Kirk. Bones brings it up before a mission and is dismissed, it never comes up again.
