Update: As correctly indicated by the overnights, NBC’s “Rosemary’s Baby” was a weak performer. The broadcast scored a 1.1 adults 18-49 rating with 3.7 million viewers.

“Rosemary’s Baby,” to put it simply, was a nightmarish performer for NBC.

The first part of Sunday’s adaptation, which aired Sunday, drew a paltry 2.6 overnight household rating. Below the combined average of NBC’s usual–and now cancelled–occupants “Believe” and “Crisis,” the number was doubtfully within the realm of the network’s expectations.

The adults 18-49 rating, which will be released shortly, is expected to fall in the 0.8-1.2 range.

NBC’s poorly-reviewed adaptation wraps its run this Thursday.
