This move has negative associations with the past, but this particular moment in network history is full of entrenched hits on the competitive nights, and I don't think there's really a safer slot for the show.
Sunday is crowded with established shows, and Fox isn't going to mess with its comedy lineup.
Monday? Not a good idea, as Dancing with the Stars
, CBS' comedies, and even NBC's dramas beating up Sarah Connor
demonstrates; the night is so crowded, House
is being moved there to support 24
Tuesday and Wednesday? Jam-packed, and Fox wouldn't be patient if Dollhouse
blew American Idol
Thursday? Against CSI
and Gray's Anatomy?
Friday, by contrast, is wide open, because the other networks have given up. CBS is just airing reruns at 9:00, for crying out loud. It's hardly ideal, but it may be the best available option.
