I was chatting about the movie with a friend the other day when it occurred to me that Admiral Marcus seems to have revived Khan for pretty much the same reason that Pike recruited Kirk in the prior movie.
Admiral Marcus seems to think that Starfleet has gotten too soft and civilized to protect the Federation from the Klingons and other threats,while Pike saw in Kirk a certain audacity and devil-may-care spirit that he thought 23rd century Starfleet was sorely lacking.
In retrospect, I kinda wish the movie had done more with the idea that both Khan and Kirk are throwbacks of a sort, and that possibly the oh-so-"utopian" world of the Federation may need a Kirk to shake things up . . . but not a Khan?
So how come Pike made right call, but Marcus went too far?
