SyFy doesn't know what it has, and therefore keeps killing its own children. It's almost as if they're afraid of success as much as failure, so they'll just continue to rely on the cheap stuff they know works - Mansquito-level TV movies and the WWE - and avoid taking any real risks.
They are the Sega of basic cable.
BSG was a success--for a while. Then its ratings tapered off and it became a money loser. And it was an expensive show, so they needed those good ratings to sustain it.
SyFy isn't afraid of success. They are afraid of expensive failures. Cheap failures are easier to recover from. Cheap successes are easier to achieve.
