1) “Best Medicine” debut, 8 p.m., Fox. Here’s a second chance to see the start of this excellent comedy-drama. It debuted Sunday after football, now repeats that hour in its regular spot. Remaking an English gem (“Doc Martin”), it sees a surgeon, devoid of people skills, hired as the village doctor. He clashes instantly with the townsfolk, including (shown here) his charmmingly distracted assistant.
2) “Will Trent” and “The Rookie” season-openers, 8 and 10 p.m., ABC. After sitting on the shelf for eight months, these above-average shows are finally back. “Trent” starts its fourth season by having Will go rogue yet again, this time when someone from his past escapes from prison. “Rookie” starts its eighth year with a story that stretches to Prague.
3) “High Potential” return, 9 p.m, ABC. After a Rembrandt artwork was stolen, Morgan linked with Rhys, a clever and cultured art-recovery expert. Now — after a 10-week break — the story continues. She’s charmed by Rhys, but also has growing suspicions.
4) “Finding Your Roots” season-opener, 8 p.m., PBS, America Ferrera, an Oscar-nominee (“Barbie”) and Emmy-winner (“Ugly Betty”), wanted to learn about the dad who left when she was 8; she learns much more, in a multi-continent search. And Darren Criss, a Broadway star, learns of a relative who had a land grant on (yes) Broadway Street.
5) ALSO: A 9 p.m. on Fox, “Doc” has emotions entwine as two young people are near death. With one exception (the cliche of over-reacting family members getting in the way), it’s an excellent hour. At the same time, PBS’ “American Experience” probes cover-ups concerning the effects of the atomic bombs dropped in Japan.
