That's no way to treat a Vette.
I found myself distracted looking for signs of the original characters to come through the noobs. The most convincing to me was McCoy and it wasn't just the familiar phrases and mannerisms.
I do have a problem with sending men to do hand to hand combat when there's no reason not to take a phaser. The other guys had guns too but they chose to shwashbuckle-WTF? Although sword fighting did play a role in TOS, it was usually for the lack of conventional weapons.
No Shat? It could of been done and wouldn't have increased the campy factor any more than writing the story around 'future Spock.'
It's a deccision that will probably be regretted after Shatner passes.
