Actually I believe he is a great character and a very good villan. Look at the character. First off I'd like to point out how genius he is. He thinks up that entire plan to get Caption Kirk and Scotty to do things for him. On top of that he knows exactly how to select words so people believe him. And no he is not a 100% misunderstood character but if you think about it from a simple view he takes "what would you do for family" and puts an evil spin on it. Also Benedict plays him amazingly :)

oh no, honey…
I think you’ve missed the point of the post.
Khan is a good villain. An excellent one, in any incarnation of Trek.
Khan is a bad PERSON which is what makes him a good CHARACTER. That was the point I’m making. People are going to turn him into their new hubby like they did with Loki et all, when, well, he’s a pretty fuckin’ bad person.
also, “Caption Kirk”
