Re: J.J. admits keeping Khan's identity a secret was a mistake
Actually, the hardcore fans just assumed that everyone wanted Khan, because it fit some preconceived notion that the hardcore fans had about what the lowest common denominator looked like. But the truth is that the hardcore fans have no idea what the general public, in aggregate, knows about Star Trek. The hardcore fans especially have no idea what the general public cares about enough to get drawn in by.
That's because Khan is the only villain in Star Trek that non-fans will recognize. If you're trying to reach a wider audience, using Khan as the villain is your best bet. It's either him or have the Enterprise encounter some killer space whales.
