I had a neighbor ask me about the movie and I told her "It's a good movie, but it's just not Star Trek".
I explained to her as if you are going to a restaurant, all you need to know is one word; Italian, French, Mexican, etc. With that one word, you know what is on the menu, how it will be prepared and how it will be served.
Sci fi is the same way, be it Star Wars, Star Trek, Babylon 5, Buck Rodgers or Battlestar Galactica. Each has it own flavor and substance that sets it apart from the others.
This movie gets at lot of that wrong.
The Enginering set would work on Battlestar Galactica, but is just not Star Trek. Huge transparant pipes, concrete floors and I still have no idea what that big bladed thing was supposed to be other than a threat to Scotty. All I could think of in these sceens was that MST3K movie with BSG stock footage that was filmed in a factory (with the sun shining thru the windows).
The space combat sceens would have worked on Star Wars, but were too chaotic to Star Trek. Dogfighting in space is what set Star Wars apart for other Sci fi of it's time, but Star Trek has allways been more like Pirates and Corsairs, two big ships broadsiding each other. Also, Phasers have allways been beam weapons, the "Blaster Bolts" here just don't look right and don't let the toy companies design your prop weapons, OK?
The Spock/Uhura pairing doesn't work because Spock's sex appeal is based on the fact that he is unobtainable. It's the Cartman Principle, you want it because you can't have it.
But the biggest problem for me is the destruction of Vulcan. The #1 reason I stopped reading comics was because of this "Re-decorating with a Flamethrower" . Whenever a new creative team takes over a comic, they redecorate the series; New costumes, new members and new curtains in the war room. But some teams can't stop there, they have to destroy everything and rebuild from the ashes. When the X-men books went back to Xavier's being a school, we got all these mutant students as new characters and I loved it. Then came M-Day and most of them lost their powers. But that was not good enought and as their buses went out the gate, they were blew up and all the characters were killed.
And that it the problem here, destroying Vulcan is a step too far. Yes you want to show your bad-ass villain is bad ass, but if you go too far you have to spend too much time expaining what you did or you just hand wave it and introduce "new Vulcan" in the next movie and never mention it again.
