Past Life

She's a psychologist who believes in ''past-life trauma''! He's an ex-cop-turned-detective! Richard Schiff wanders in from The West Wing to be their boss! Together, they make a lotta hooey! Their clients have debilitating visions that also help the heroes solve crimes. Thing is, star Kelli Giddish is so distractingly pretty and charming, even to other characters, that it adds a layer of deconstructive interest to a silly series. (The pilot first airs on Tuesday, but repeats tonight along with a second episode.) C+Ken Tucker
