I think every Firefly fan wishes there was more of this amazing show, but it's clear that this will never happen. The show's popularity has grown so much in the years since it was canceled, I think it would be feasible for a "sequel" of sorts. NOT a remake, but a show that takes place several years after Serenity the movie. It could have a mostly new cast, but bring in the old crew as recurring characters. If they did it right, and the right people were involved, I believe it could be as great as Firefly itself. What do you think?
Which cast members would be absolutely vital? Personally, I think River would be vital, but the others could come and go. Yes, even Mal.
