When NBC canceled Southland, the outcry from anguished fans reached the ears of someone at TNT, which picked up the show after only a few weeks. Next Tuesday, January 12, TNT's going to show a 2-hour "extended version" of the show's pilot episode. There'll be 13 more shows, including six brand-new ones. (The new ones begin on March 2.) Let's face it, folks. Cable's the place for a show like this, and some of the earlier episodes will have some of the previously omitted language restored. Check it out.
