I remember a very vocal and significant number of fans protesting the cancellation of the show and campaigning to have it brought back.
Very true. Even some of the stars took part in the rallies in LA.
If only those same people were as vocal for the '91 DS to be a continual part of the Fests. And if we can believe postings on the Internet, the '91 DS supposedly gained a lot of fans when it was frequently rerun on the Sci-Fi Channel. But by that time the '91 show was all but forgotten so far as the Fests went.
What will be interesting will be to see how the Depp/DS film is regarded in fandom after it's been around for 25 years. Though many of us won't be around to see it - or even if there still is an organized DS fandom...
