1) “Perfect Harmony,” 8:30 p.m., NBC. The Perpetual Praise mega-choir is overwhelming. “They are the Death Star of church choirs,” Dwayne says. They have platoons of singers, fog machines and an arena-like facility with giant screens. Now the tiny Second First Church choir is lured into a challenge … while its conductor (shown here) is having a bad hair day. After a so-so Halloween episode last week, “Harmony” reverts back to form, as the best new series on a broadcast network.
2) “Will & Grace,” 9:30 p.m., NBC. Skirmishes are happening everywhere. Grace battles the condo president … Karen battles her ex-husband’s brother (Patton Oswalt) in poker … and Will and Jack battle each other about receding hairlines. Much of this is loud and blunt, which is the show’s style. In the wrong hands, it would be awful; but with sharp writing, a gifted cast and TV’s best comedy director (James Burrows), it’s sometimes hilarious.
3) “Young Sheldon,” 8 p.m., CBS. Missy, Sheldon’s twin, has been a fun afterthought, occasionally making a wry comment. But now she gets the focus: It turns out she’s got a good fastball; her dad, the football coach, insists that the baseball coach (Craig T. Nelson of “Coach” fame) give her a try-out.
4) “Legacies,” 9 p.m., CW. This show was bumped last Thursday – which happened to be Halloween and the 20th birthday of Danielle Rose Russell, who stars as Hope. Now it’s back, with things that will make us think it’s still Halloween. That includes a samurai hunting a demon that possesses its victims.
5) “Doc Martin,” any time, www.acorn.tv. A week before the season-finale, key questions remain: Can the doctor – with a blood phobia – satisfy an examiner and keep his license? Will his receptionist and the barkeep go ahead with their marriage? Nothing gets resolved this time, but there are some dandy mis-steps – a cellar crisis … a bloody kitchen encounter … and a medical three-way that involves doc, vet and dog. It’s all fun, in a low-key way.
