A strong, charismatic, intelligent, sexy man with a superiority-complex and a tendency to use violence - yes, nothing like Khan at all.
Those attributes could be applied to James Bond as well. And I was more talking about how it worked as a whole. It's just as with the main characters compared to their original counterparts, some work and some don't.
Kirk, Spock, Bones, Uhura, Pike ... they were all very convincing. But Scotty and Chekov? No way! The same goes for Cumberbatch. I really wish they had left Khan alone and made Cumberbatch play somebody - anybody - else.
