Ask fans what makes Star Trek great, and you'll get many different answers. Plenty of fans will tell you that DS9 is their favourite series, yet that is the series which lost more viewers over its run than any other. Star Trek was saved by a writer who didn't like a number of aspects of TOS. He put a significantly different spin on it - to the point of, in his own words, breaking Roddenberry's mould. As he says, "art is a dictatorship, not a democracy." I'd much rather watch something written by people following their own vision, rather than trying to cater to what they believe fans want (which would not be representative of all fans, and possibly not even a majority).
