My principal issue is that making the movie the Wrath of Khan stole a lot of its emotional resonance - Kirk hadn't really wronged Khan, his relationship with Spock is in its infancy.
why it was done that way. To create a different story. "Into Darkness" is neither "Space Seed", nor "The Wrath of Khan". It's a new adventure for Khan, and a very different story arc for the characters.
And I thought STiD had plenty
of emotional resonance. Different
emotional resonance, but no less emotional. For me, at least. Until that tribble revived, I was sure Kirk was staying dead... at least until the next movie.
