I was a fan of Fantasy Island before I'd seen a whole of Star Trek. I had seen Space Seed in reruns after the show had been on a couple of years and was overjoyed when I heard that he would reprise the role for TWOK.
Kahn was a wonderful character. I was actually sad to see him die at the end, although the way the character had evolved it was inevitable.
Yet another big loss. Trek is losing it's soul.
