Last year, CBS went for a bloodbath, canceling seven series, including some decent performers like The Ghost Whisperer and The New Adventures of Old Christine. The network, which is yet to find a series that does as well as Ghost Whisperer in the Friday 8 PM slot, is not expected to go for such a dramatic overhaul this year. I hear a deal is almost done for RULES OF ENGAGEMENT to be renewed as CBS seems to be summoning all of its veteran comedies as flagship Two and a Half Men faces an uncertain future. There is even talk about possibly bringing $#*! MY DAD SAYS sans star Jonathan Sadowski. Even long-forgotten legal dramedy THE DEFENDERS is not completely dead. As one insider noted, the show starring Jim Belushi and Jerry O'Connell did better than any other CBS series in the Friday 8 PM season this season. Things don't look good for midseason comedy MAD LOVE, though CBS brass loooove Jason Biggs, while CBS' other midseason entry, crime drama spinoff CRIMINAL MINDS: SUSPECT BEHAVIOR, is at 50/50 as its performances has been largely disappointing given its pedigree. As for CSI: MIAMI and CSI: NY, word is that the entire CSI franchise, a big off-network and international seller, is safe for next season.
