Dr. Keith Ablow (ab-low) is a psychiatrist who looks either like Tony Randall's son or Howie Mandel's more serious brother. He explores his guests' emotional wounds with an air of scrupulous earnestness that suggests a dignified professionalism, as if he were running an expensive clinic or sanitarium. But his very lack of showbiz flashiness (some might say vulgarity), even when doing a show on the spectacularly strange John Mark Karr, can make for a disappointing TV experience. Compare this with the ripe, entertaining bluster of Dr. Phil. Ablow could afford to be more of ablowhard.
