I don't wanna be the guy who's like "IT'S KHAN!" but it's totally Khan.
I'm not seeing it.
I think Khan has been a red herring as the villain. The problem with reprising Khan is everything about what made him such a great villain in TWOK hinged on events that do not apply at all in the JJ-Verse. There was a past between Kirk and Khan that mattered. Time mattered. TWOK worked on themes of aging (Kirk), vengeance (Khan), and sacrifice (Spock).
I agree entirely. I'm amazed so many people have missed this and ignored the fact that a JJ-Universe Space Seed needs to happen before events akin to TWOK.
