It would have been fun to be with other Trekkies, but I refuse to pay a premium price and go and sit in a mildewy theater for what is basically a TV show from the 1960s that I already have on DVD.
It sure is an interesting phenomenon. The film distribution and exhibition industry has been worried about losing market share to the home entertainment biz since VHS. It's been interesting to see the social element to screening parties like this take effect. As good as the presentation at home is, people (some people) still want to have that shared experience that only a theater enviroment can give.
