Why make Starbuck a woman? Why didn't Heath Ledger play the Joker exactly like Cesar Romero or Jack Nicholson? Why cast Lucy Liu as Dr. Watson?
Sometimes it's just fun to take an old concept or character and put a new spin on it . . . .
In principle I agree, but this isn't quite a comparable situation. There is no continuity aspect between the different shows you cite. Here, it's been made very clear that prior to 2233, the universe was the "prime" (TOS) one. Sure, the look of ships and technology change to suit budgets, but the people shouldn't. No one is going to switch genders. If Khan appears in this movie, he should be basically the guy we saw in Space Seed: a former middle eastern dictator who was ousted and exiled. He can't suddenly become a white British chap with an attitude to match his voice.
