"My name is...KHAAAN!" took me right out of the movie. It was far too dramatic a delivery for a name that meant nothing to the crew. It was obvious to me that the writers were speaking - no, yelling - directly at the audience. It was a "faaaaake!" It's like saying "My name is... JOHHHN!" "Yeah, okay, John who?" That's where HISHE got it right. He could have at least said "Khan Noonien Singh" and be more introductory - I mean, is the name "Khan" really like "Cher" even after hundreds of years? No one else is or was ever named Khan? For three hundred years? Unbelievable.
"Space Seed" and "The Wrath of Khan" wrote about the discovery and rediscovery of who he was and in a much more believable, well-written and organic way. Spock and Kirk did the research in "Space Seed." It was left to Chekov to say the name in TWOK. Yeah, okay, I know Chekov wasn't really there for "Space Seed," but it was more believable anyway. It was forced in STID.
In fairness, I looked up the script to "Space Seed:"
Khan: Khan is my name.
Kirk: Khan. Nothing else?
Khan: Khan.
So apparently, it has a certain consistency, and Khan may think he is like Cher in STID, but I still think it was handled far better in the TOS episode and movie without the forced recognition implied by the dramatic delivery. I think Khan was merely being evasive in "Space Seed," so he was clearly NOT expecting or wanting to be recognized so quickly by name.
yeah, I couldn't have said it better my self. khan means nothing to these new crew so why the dramatic delivery of the name by cumberbatch. it was definitely of us the audience and that took me right out of the film.
In the chaos, Khan and his people escaped Earth in a sleeper ship. He has no idea how history has portrayed him since then, however sketchy the records of the era are. So in "Space Seed" he had to play it cautiously: do these people really know who I am or not?
In STID, Khan has had a while to understand how he's understood by history in the time he's been asleep. So, he's less clueless about it than he was in "Space Seed". That said, he must've been well-known enough for Section 31 to think it prudent to drastically alter his looks (at least in the comic book) and create an alias for him. So, while I'm not fond of using non-canon to explain things on screen, if Khan's looks were altered, that would explain Kirk's lack of recognition of him even when he said his name.
The reason I don't like the comic book solution for his looks is that's pretty serious stuff. It's mutilation, actually. So on screen, if it had been the intent of the writers to go that path, I can't believe Khan wouldn't have mentioned what was done to him to Kirk as he vented.
As far as how he said it goes, as I said above, he's a proud man who's probably identifying himself to someone as who he really is for the first time since he was essentially captured. It had to feel good for him to say that. There had to be a release of great emotion. Finally. The forced charade is over. "My name is: Khan."
