I think another important factor is the price tag of the show. 24 is a big action show, a movie every week, with a high price big name actor, and it's ratings are crumbling.
Ratings aside, I think the bigger factor is the announcement this past week that Fox wants to do a 24 movie, but it can't do it with a weekly series underway. So if there's more money to be made in the movies, Fox could take 24 off TV and launch a movie franchise with it (though since presumably the film would be a real-time adventure taking place over 2-2 1/2 hours, one wonders if they could keep calling it 24).
"Could go either way": FlashForward (ABC), Heroes (NBC), Human Target (Fox), Medium (CBS), V (ABC)
That makes no sense. I thought both Human Target and V were said to have done quite well. It's not V's fault its network put it on hiatus for 4 months. And Human Target last I heard was a big hit. Or is it just because they're big and splashy fantasy shows that it automatically puts them on the endangered list?
Once again, the only mainstream network shows I bother watching are all listed in the "on the bubble" category. I often wonder what it would be like if I was devoted to, I don't know, Desperate Housewives or something.
