It was a huge gamble and Battlestar didn't have nearly the following/history that Star Trek does.
What do we base this new series on? Do we want it like TOS and/or TNG? Do we expect it to be more like the movies (more action oriented)? How much exploration vs continuing plots?
I agree that the premise of Voyager was the most interesting of all the series. It was poorly written and executed, but the premise was great. The best star trek, IMO, is the last three season of DS9, but even they fell short of what I would have wanted.
I don't know what I want so I don't have an answer.
