Mike Hughes on TV

1) “Irrational,” 10 p.m., NBC. As one of this fall’s few new, scripted shows, this had big expectations. . The first episode was terrific; the second had a wildly unlikely finish. Now this third one bounces back neatly: A skilled pilot crashes, raising suspicion. (In truth, this episode says, there hasn’t been a fatal crash of a major airline in 14 years.) Our hero, a psychology professor, visits the crash site (shown here) and discusses some fascinating human quirks. Read more…

1) “Professor T” season-finale, 8 p.m., PBS. This is basically a case-of-the-week series, with clever crimes solved by a criminology professor. Along the way, however, it has planted secrets among the police: Lisa (Emma Naomi, shown here) had a secret romance with Dan; their boss has a secret one with an undercover cop. Dan raged about Lisa’s secret shot at promotion … while he was secretly moonlighting with thugs. It all explodes tonight, in a terrific finish. Read more…

1) “Great Chocolate Showdown” finale, 8 p.m., CW. This amiable Canadian show has become more American since adding the CW mini-network. This year, seven of the 10 contestants were from the U.S., including the final four. Last week, Tim Eford, an Atlanta cop, was eliminated. That leaves Mike Casner, 38, a Chicago doctor; Ashlee, 33, a Baltimore medical assistant; and Kristen Washington (shown here in a previous episode), 23, who drives food delivery in Jackson, Miss.

1) “American Masters.” 9 p.m., PBS. Back in the late ‘80s, one man was filming jazz great Max Roach; another made audio recordings of his memories. Much later, they merged, adding old clips and new interviews. Now we see a vivid life, spanning genres; Roach (shown here) ranged from the bebop masters (Monk, Miles, Dizzy) to a rapper. Alongside great music, we gret glimpses of friendship (Clifford Brown), romance (Abby Lincoln) and agony. Read more…

1) “Hell’s Kitchen,” 8 p.m., Fox. Last week’s opener left Gordon Ramsay seeming oddly pleasant. The women edged the men via a tiebreaker and no one was sent home. Now each side has to work on a dinner service and Ramsay returns to his screaming mode. Then “Lego Masters” (shown here) has an unusual challenge: Turn plastic bricks into playful home for real kittens. Read more…

1) “Quantum Leap” season-opener, 8 p.m., NBC. Fresh from a strong first season, this leaped into its second one before the strikes betan. It also shifted tone. Now there’s no holographic know-it-all to tell Ben what happened in the time he’s visiting. And this hour adds humor, when he crash-lands with a chaotic crew. It’s a sharp start with excellent guest stars, including the stars of “Manifest” (Melissa Roxburgh,shown here) and “Midnight, Texas” (Francois Arnaud). Read more…
