I finally got to see this last night and gave it a "Very Good" rating. If the goal was to give the franchise a reboot for the next generation then I would have to say it's a success. It's a young and sexy cast and it was apparent that each actor respected the character they were playing.
So what saves it from an "Excellent"?
1) To quote Janeway "Time travel gives me a headache." Seriously, enough of it already!
2) Spock/Uhura: While I do like this pairing (BTW, there's some excellent fanfic out there if anyone is interested) the timing is completely off. I find it hard to believe a man uncomfortable with his human heritage would engage in a love affair with a human woman. Sure, later on I could see it happening but not to the guy who went off to learn the Vulcan discipline of Kolihnar after the original mission. Still, the fanboys who wanted to see Spock "get some too" had to be served so there you go.
All that being said if you're going to do a reboot this one was done right unlike some others (ahem, Trek Lit). No major characters were killed (I'll miss Amanda
) and the film ended on a hopeful note despite the tragedy. As for the actors each performance was like a love letter to the original charcter. You could tell from the way the actor who played Spock stood to the way "Bones" said "Dammit Jim" that they were in love with their characters and wanted to do right by them.
Also, it was great to see Nimoy again. "I have been and always will be your friend" was an amazing moment and it was hearatbreaking that the younger Kirk had no idea what he was talking about. "Thrusters on full" indeed.
All in all I think it was a great tribute and a lot of fun to watch. I'm looking forward to seeing what happens next.
