Aired on: AMC, fall 2010
A brooding, slowly unraveling mystery steeped in the paranoid thrillers of the 1970s was maybe never going to be a breakout hit. Those who stuck with "Rubicon," however, were rewarded with deeply drawn characters and an unbelievably tense mood, even if the final revelations fell a little bit flat. The finale was also constructed in such a way that although its fate was undecided when it aired, it could serve as a series ender. That helped soften the blow a little.
