I was thinking. At the beginning of the movie, Nero goes back in time and attacks Earth, but Kirk's dad saves the day. However, why would Nero then go forward in time and attack Vulcan instead? Why not go back in time again and attack earth again?
Well, what if Nero first (from his point of view) went back in time to attack Vulcan? Kirk stopped him, so Nero went further back in time to attack Earth and kill Kirk. Nero's ship was damaged from the battle at Vulcan, which gave Kirk's dad and the Kelvin the chance to kill Nero once and for all.
So Nero experiences events in the opposite order as Kirk does. At least that's my crazy theory about the movie.
