You can make a case for Dresden, Stargate: Universe, Caprica and I'm sure a few others. Siffy has indeed proven that they don't have the cash to support many expensive SF shows, and make up for it with comparatively cheap reality shows, and wrestling (the cheapest science fiction there is).
Wrestling is not science fiction at all. It's just play acting at being bad boys and girls.
