Oh please - name one true science-fiction show on one of the major networks that's lasted more than a season? The last space-based science fiction show tried on a major network was Ron Moore's BSG2003 on NBC. After receiving high ratings for cable-based Sci-Fi network; they tried it on NBC in a prime spot where it proceeded to get the LOWEST ratings in that spot.
The truth hurts.
I find the truth refreshing, honestly. "Star Trek" won't work on traditional TV. If we want it, we're going to have to pay for it. Pretty concise message.
