CHAOS [CBS, Fridays, 8/7C] is a spy dramedy that seeks to expand CBS’ number of procedurals and comedies. In that mix, it is, apparently, trying to duplicate the drama/humor mix that makes USA Network the most successful basic cable network. It’s a laudable attempt, but the comedy too often feels forced onto the procedural. When the two don’t overlap – which is seldom – each works just fine. It’s when the two are jammed together that things fall apart and chaos.
