Petty interpersonal conflicts, especially in the hands of people afraid to have any other thematic content, are dreadfully cliche by now. That would explain why it fits into a network's comfort zone. In particular, it seems as though it is imagined more as a Firefly incarnation. There was an awful lot wrong with Firefly and it seems highly unlikely Syfy would have any idea how to fix it. And it seems even more unlikely that they could do the jokes as well as Whedon.
On the other hand, maybe they'll actually update Blake's Seven. I've never seen that and I look forward to seeing either the original or a contemporary adaptation.
