Bad ratings are bad ratings. Can't blame a station for people not tuning in, especially for one they advertised as much as they did (and they most certainly did despite the rabid fanbois protests; I remember seeing the ads on other
channels at the time).
I'm personally disappointed that the Adventures of Brisco County Jr. was cancelled, but it was hardly Fox's fault.
People just can't seem to accept that their personal preferences in a show aren't necessarily the same as everyone else.
