CBS's craptacular new cop show Cold Case airs its second episode tonight. It would be possible to create a detailed account of why it merits the description "craptacular," and that account would include the protagonist's really bad Kirsten Dunst impression and the pilot's use of a watered-down retelling of the Martha Moxley case, but, really, all you need to know is that it's basically the BBC's Waking the Dead only without the compelling cases and interesting middle-aged characters.
