Showtime's Homeland, which swept this year's Emmy Awards, returns this weekend -- as does another Showtime drama, Dexter. Critic David Bianculli says there's a rich bounty of returning series -- and Homeland is the "most topical and meaningful drama on television."

Critic David Bianculli says of all the new programs premiering this fall, there isn't on you have to add to your weekly viewing lists. The best new show, he says, is Emily Owens, M.D., which is just like Ally McBeal if she were a doctor instead of a lawyer -- but it's graded on a curve.

Monday night on PBS, American Masters presents a two-hour biography of Johnny Carson. Carson retired 20 year ago this month, and vacated a throne that TV critic David Bianculli says no one has managed to claim since.
