As for the OP, Khan is a character, not a situation. The whole point of the reboot was to put familiar Trek characters in new situations. Khan still has his Eugenics Wars backstory, which is more than enough reason to be pissed off at the peoples of Earth. Overthrown and exiled to space, now back for revenge.
Where are the voices of these characters? What did this movie say? What commentary was it attempting to reflect upon our society?
Spock came out of the closet, TOS analogy-style. I'm amazed often it zooms over the heads of fans of the original show! It was much more personal than "save the whales" or "the Berlin wall falls in space," but I'd say it's a very important message nontheless.
