Shame on me for not posting this earlier. This is a TV adaptation of a 2010 movie. It is about a pathological criminal family. It is violent and profane and absolutely enthralling. Ellen Barkin plays the devious and manipulative matriarch of a totally amoral gang that preys on society and each other. It is on TNT but apparently one can watch the whole thing on "On Demand".
Damn, I was hoping this was Stew waxing nostalgic for Marlon Perkins.
