Mike Hughes on TV

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…

1) “Only Murders in the Building” finale, Hulu. A great season concludes with Oliver (Martin Short, tighty) frantically trying to stop Loretta (Meryl Streep) from confessing. She’s just trying to protect the son she gave up at birth, but Oliver is convinced that neither is the killer. Also, he loves her AND needs her to co-star in his musical, alongside Charles (Steve Martin, center, alongside Selena Gomez) and others. Now we should learn who the real killer is … and, maybe, how the musical does. Read more…
