Exactly. Most Trek stuff is for Trek fans only. Chances are you won't like most Trek shows and movies if you don't like the Trek universe in the first place.
Khan is not just a good Trek movie; it's a good movie period. I don't see how anyone who claims to be a fan of scifi-drama can not like Khan.
And Ricardo Montalbahn is a GREAT villain.
Shit, I have to watch it after work. I'm all fired up now.
