Do you think that the cons play a role in keeping their friendships alive and growing? It's my impression that some of those relationships have gotten better from working together in a different situation!
We were just saying the same thing about the highlander-community site, too. It's been a number of years since the last film, and yet we keep meeting online to have fun and support one another. We were brought together by shared values, values reflected in the show and films, I think. So, even if the franchise were gone, the values still remain. I also think that if the franchise gave up the ghost, we might not get new members, but the old members would keep meeting until the last quickening went up to the Source.
