Once upon a time, I'd watch FX's Sons of Anarchy begrudgingly because it was popular. Now I'm watching because it's good. As in bad. As in: bad things happening to bad people. Consequences = drama. And that's rarely been more evident than as the fifth season gets underway Tuesday (10/9c), with the motorcycle club torn apart from within and without, capped by an act of retribution that's horrific even by this show's violent standards.
