I picked up a cheap copy of Trekkies today, and watched this arvo.
Of the two docos, this one was more about the extremes of fandom, such that at times I felt like I was watching a Christopher Guest style movie rather than an actual doco!
There was some concentration on the woman who was the juror at the Whitewater trial some years back, who wore her Star fleet uniform each day, and captured a lot of media attention. She was hardcore, to say the least - she seemed rather more humourless than a lot of the other fans interviewed.
Slash fans got a mention, as well they should, because it was Kirk/Spock that was the birth of the slash phenomenom. A couple of slashers were interviewed - one was photographed with voice and identity disguised, she was that cautious about being recognised! Given the subsequent boom and acceptance of slash in the years following this film, I wonder if she would be less paranoid about being outed as a slash fan? I don't judge her for it, of course, there is still a ridiculous amount of stigma attached to being a slash fan.
The loveliest comment about Trek fandom (and I feel this could apply to fandom in general) was that all sorts of people, regardless of sex, size, colour, age, religion, sexuality or political inclination can go to a Star Trek convention and feel at one with all the others attending, and not feel judged as they might out there in the real world.
