Midway through its third season, Justified has been renewed for a fourth, FX has announced. The news shouldn't come as much of a surprise, as ratings for the show continue to climb, with this season's viewership up 8% over last year's. The show has proven a solid performer for the male-skewing network that has recently been trading on fare like Always Sunny, Sons of Anarchy, and until recently, Rescue Me.No word yet on when the season starts shooting or airing, but with the season three finale not happening until April 10, one can bet that it will be no sooner than November or December of this year.Justified has proven itself to be a fun, straightforward show that balances out serial and procedural elements that are buoyed tremendously by both rich writing and strong character performances, as Margo Martindale's recent Emmy grab would indicate.
