Overall, great movie... my son and I really enjoyed it.
Pros
All the new actors really did a good job playing up to their predecessors.
Spock was great, but McCoy was probably my favorite of the bunch.
Cool space debris after battles.
Cons
The Spock love interest? Did NOT see that one comin.
Still trying to reconcile the space-time continium disruption in my head. (I think I've decided to try not to think about the two instances of Spock)
A red dinosaur on Hoth
Other comments...
I heard that all the actors that signed on had to agree to at least 3 films. So now that everything has been time-disrupted, the writers basically have free reign to ignore or redefine the storyline history going forward!?
