Looks like I was right. Sci-Fi shows always get Canceled. They would rather see more violence , blood and killing. You ever notice what passes as entertainment on CBS? CSI shows have murder after murder in them. Without a trace , Numbers, Shark, all have murders, violence & killing. Even Jericho, which I really liked , had a sci fi type plot and was first cancelled and brought back this year to finish the story, after thousands protested the cancellation. I can remember in the 60s when CBS had a lot of sci-fi shows like Lost in Space, Land of the Giants, Time Tunnel. Now you barely get 2 episodes of a sci fi show on and they cancel it.
