The state of the world may be rotten, but it is important to, as Fred Rogers once said, look for the helpers. Fox's "Best Medicine," which might remind you of "The Pitt," is a series by people who believe the world isn't beyond moral repair. Josh Charles stars as Dr. Martin Best, a hot shot MD who skips out on a lucrative Boston hospital position to tend to the maladies of Port Wenn, Maine's mostly friendly citizenry. The people of Port Wenn are generally willing to accept Best as their new local doctor, but he gets resistance from skeptical schoolteacher Louisa Gavin, played by Abigail Spencer. If you've been watching television for the last few decades, you've seen her on everything from "All My Children" to "Gray's Anatomy."
