It wasn't us.....really
Star Trek is dying because it's not bringing anything new to the table. For anything new or exciting, there was Farscape. I personally think that Voyager killed Star Trek. Voyager started out ok, and then they crapped on Kes and made Janeway a complete biotch. The series became unwatchable. Enterprise didn't have the personalities of Voyager (cool people like Paris, Kim, Tuvok and Torres), but it was pretty solid. When Voyager descended into the planet of the week format, and stale characters (which the admission of Jeri Ryan couldn't save), people had enough and got bored.
Enterprise was so very dramatic, I would have liked to see more jovial behovaior, following more the TOS attitude than the very sombre Picard. DS9 was more loose with Quark, and Voyager had it's lighter moments, but it all got bogged down by the complete seriousness of it all. Perhaps the time off will do good for the franchise, till someone feels it necessary to revitalize it.
Star Wars, on the other hand...cannot be saved...and could never survive the TV format. Someone need to whack George Luces really really hard.
