Then why do they insist on using the names of good sci-fi series to make new stuff? Obviously there is a demand and they are cashing in on it.
BTW, Firefly was a great series but in a "hey this is fun" rootin' tootin' six-shootin' way, not in a serious sci-fi way. Kind of like Dark Matter is now. In fact Dark Matter is almost exactly like it, except everyone has memory loss.
