Poppy Montgomery plays a detective who can’t forget anything – literally – on “Unforgettable.” Michael Emerson plays a computer software billionaire who’s developed a new program that identified violent crime participants but apparently can’t distinguish victims and bad guys – major design flaw -- in “Person of Interest.”

So far this season, both shows are averaging about 14 million viewers.

The only other show CBS has picked up for the rest of the season is its Monday comedy “2 Broke Girls,” which is the most watched new series of the season. CBS yanked its other new fall comedy, “How to Be a Gentleman.” That means “A Gifted Man” as the only new CBS series that debuted in the fourth quarter still waiting to learn its fate.
