It's cancellation season thanks to the network television upfronts this week, and today's CBS portion was nothing short of a bloodletting. On the chopping block were popular-but-not-sustainable shows like 'Cold Case' and the funny Julia Louis-Dreyfus comedy 'New Adventures of Old Christine.' Also coming to an end will be the reign of Jennifer Love Hewitt and her show 'The Ghost Whisperer,' a paranormal drama of sorts that has managed to survive since 2005.
