I saw this opening day, and a few things stand out to me.
1. Kelvin, I would belive the alternate timeline story if not for Kelvin. Please someone explain how that bridge fits between the NX-01 and the NCC-1701? At least with Enterprise they tried to make it look older tech wise than TOS, but for Kelvin Abrams threw cannon out the window. IT looks like a kitbash between Star Trek VI's bridge and the Reletivity honestly.
2. Nero's went back and time and altered the tmeline. Now correct me if I'm wrong here, but shouldn't someone have said hey wait a minute. You would think reletivity would intervene, or at least a timeship in generals to prevent this drastic change.]
3. The Technology, how did there technology jump 100 years ahead of its time, are we to belive that just becase on star ship was destroyed by an unknown vessel (happens alot in classic trek) that star fleet somehow made there tech look like it would normally by the time the Enterprise D launched.
4. Why did they use the shuttle to get to the ships? Its an emergency, and star fleet has transporters, star ships have transporters, wouldnt it be easier and faster to just beam the crew to the ship?
5. Kirk goes from cadet to captain from one mission. This is totally unbelivable
6. How the hell is Checkov on the ship, he would still be in Elemtry school in the late 2250's remember in 2267 he was a raw engisn freash from the acadamey.
