Spock seeing Vulcan's demise from the other planet as if its in cinemascope. It should not have even been visable.
Agreed. Without a telescope for Spock, this was impossible. Even for dramatic license, Vulcan and that planet would not be as close as Endor and the Death Star II, unless that's what Abrams was going for. I'll give you this as a plot hole only so that Spock Prime meets Kirk, so they can meet plot hole Scotty the Clown. If Nero had been smart, he would have kept Spock Prime close so he couldn't cause any problems. Also, since Nero knows his history (future?), he would remember Spock is half human. Watching Earth get destroyed as well would be like two daggers through his heart, rather than just watching Vulcan eat it. Guess the filmmakers overlooked that one.
In Abrahams (and the writers) defense. The original cut of Star Trek TPM did show a planet or moon in very close proximity to Vulcan.
So there is definatly a precedent.
