That's one way to look at it, but I still like to look at it as "Fox is an evil network run by evil bastards who cancelled Firefly, Space: AAB, Strange Luck, Alien Nation, Dark Angel, Sarah Conner, Dollhouse, Tru Calling, etc, etc, etc..."
Every show gets cancelled sooner or later. FOX deserves credit for
buying that many genre shows in the first place. A while back I tried to work out the numbers and I found that of all the broadcast networks, FOX had the highest percentage of shows that were SF/fantasy, edging slightly ahead of the WB. NBC and ABC were roughly tied for third, and CBS a distant fifth (I didn't count the CW since it was too young for useful statistics).
Not to mention that corporations are made up of people, and the people who canned those earlier shows, notably
Firefly, were long gone before
Dollhouse came along. Really, the current FOX regime deserves great credit for giving
Dollhouse two full seasons, when normally it would've been pulled due to poor ratings after less than one. They really went above and beyond in supporting
Dollhouse, and it's grossly unfair and wrong to condemn them for its cancellation. Ultimately shows get cancelled because
people don't watch them. If the audience doesn't come, there's nothing the network can do. It's very expensive to make shows and they can't be made unless they can be paid for.
They really do seem to have a strong record of buying a genre show only to ditch it like a hot potato within a season or, at most, two.
The same goes for just about any other network -- and any other genre. It is the nature of the industry that the majority of shows get cancelled quickly. It's not about FOX and it's not about genre. It's just how television works. I mean, hell, why do you think we keep getting new shows every year?
Because the old ones get cancelled. The current season's only a few months old and we've already seen a bunch of brand-new shows get canned, including
Allen Gregory, Charlie's Angels, Free Agents, Friends With Benefits, How to Be a Gentleman, Love Bites, Man Up!, and
The Playboy Club (which was pulled after only 3 episodes). So it's silly to attack FOX for doing something that all networks do.
