While Justified never ceased being one of the best shows on television, it entered into a third season slump. After a near-perfect second season, featuring one of the greatest TV villains, Mags Bennett (Margo Martindale), it couldn’t help but underwhelm in its junior year, replacing her with a slew of uninteresting baddies. Season four, however, is proof positive that a show can redeem itself. It has remained Harlan-centric villain-wise, with the exception of Mike O’Malley’s Detroit mobster Nicky Augustine, who is a vast improvement over who he replaced, Adam Arkin. No offense, Arkin… but O’Malley is killing it. Villains aside, the reasons why Justified continues to triumph this season is because of the consistently amazing writing and direction. The dialogue is nearly poetry, with Boyd turning phrases that sound as if they come out of Shakespeare’s notebook – Nicky even tells him this week, “I’m going to need Google Translate on my phone if I’m going to keep talking to you.” This week’s episode, “Peace of Mind,” co-written by Taylor Elmore and Leonard Chang and directed by Gwyneth Horder-Payton, is no exception. While perhaps less action-packed than last week, it features snappy dialogue, macho encounters, and a fluidity in the transport of people and places as the law and the criminals both chase after Ellen May (an excellent Abby Miller) who is also on the move – from Noble’s Holler, to her former pimp’s house, to the church, to Lexington.
