Ah, the old warring partners engaging in witty banter as they investigate crime on TV. It's a set-up older than the medium itself. So you'll have to forgive USA's latest original series, Common Law, which goes back to this standard format, one shared by network-mates like White Collar, Suits, and (my favorite) Psych.
What sets Common Law apart from these other shows is it's the only one whose premise centers entirely on the unstable relationship of its main characters. Detectives Wes Mitchell (Warren Kole) and Travis Marks (Michael Ealy) are such an explosive pair, that they are sent by superiors to couples therapy to work out the kinks in their dysfunctional five-year partnership.
