Re: Do fans want the prime timeline back? Part 2: Poll edition.
The end of the movie, Kirk ties it up nicely by saying "we shouldn't try to seek revenge, to act on our initial anger." EDIT:So anger would appear to be the connective tissue between Marcus and Khan and Kirk and Spock. Marcus is motivated by preservation due to his anger that Nero destroyed Vulcan. Khan is angry for being used, Kirk and Spock for someone dying. Acting on the initial anger (re: revenge)
Three humans and a half-human acting realistically human. That hasn't happened very often since 1987. No wonder it is throwing you for a loop.
