There are questionable full-season pickups and then, there are the no-brainers. This one is the latter: CBS has picked up the back nine episodes of Person of Interest, the network’s latest procedural that stars Michael Emerson and Jim Caviezel.

The drama about a former CIA agent and mysterious billionaire who attempt to prevent violent crimes has averaged a 3.0 rating/10 share in adults 18-49 and 14 million viewers.

CBS also ordered the remaining nine episodes of Unforgettable, the Poppy Montgomery starrer about a former police detective with a rare ability to remember everything. The drama has averaged a 3.3/8 in the key demo and 13.9 million viewers.

The network has already given a full-season commitment to 2 Broke Girls and canceled How to Be a Gentleman. The jury is still out, however, on A Gifted Man starring Patrick Wilson.
