There’s a centerpiece scene in the series premiere of Showtime’s “Your Honor” that’s among the best of the year. A New Orleans judge named Michael Desiato (Bryan Cranston) has returned home to find his son Adam (Hunter Doohan), rattled and apparently injured. The boy can barely speak, quietly muttering what happened that morning to his powerful father through tears. Adam was in the Ninth Ward, visiting the spot of his mother’s murder, which happened a year ago. As he was driving away, Adam had an asthma attack, and crashed his car into another young man on a motorcycle. He went to help but watched the life drain from his eyes. And then the scared kid drove away. Doohan is strong here, but it’s Cranston who captivates, finding the balance between a father’s emotional response and someone who knows every aspect of the legal process. While comforting his only child, he starts using words like “shock” and “trauma,” already building a reasonably plausible story to protect his boy. It’s a great scene as written and it’s elevated by Cranston’s smart choices.
