1) “Best Medicine,” 8 p.m., Fox. In the opener, villagers met Dr. Martin Best. They promptly dubbed him “Doc Martin” … and promptly decided they don’t like him.

Like the opener, this deftly mixes comedy, drama and small-town charm.

In this opener, he skis to the South Pole, climbs an ice cliff and visits a remote research station.
4) “Harlan Coben’s Final Twist,” 8 p.m., CBS. After airing exactly one episode of this true-crime series, CBS has shifted its plan.
