I will only consent to a Trekkies 3 if it involves DeForrest Kelley coming back from the dead and punching George Lucas in the balls.
De Kelley was far too much of a gentleman to do that!
I'm disappointed that Trek Nation never saw the light of day. The trailer for that looked really good, and I found it moving. I've never seen Trekkies, but from what I've read, it seems maybe to concentrate on what could be considered the negtive sides of fandom. Trek Nation seemed more of a celebration of fandom.
