Don't call Sons of Anarchy gritty.It's not that the word doesn't accurately describe the show's bloody violence and testosterone-fueled moral darkness. Rather, Sons creator and executive producer Kurt Sutter just thinks the word has been used to death. And, Sutter says, all the gun-running and motor-revving is really just background noise to the show's family drama.That was never clearer than in the show's 90-minute Season 2 finale, in which a son loses his father, a father loses his daughter and two fathers have their sons taken from them. The most emotionally gripping of those losses: Jax (Charlie Hunnam) crumples into the arms of his former nemesis/stepfather Clay (Ron Perlman), as they watch kidnappers speed away in a boat with Jax's son.
