NBC got pretty good mileage out of its “Mockingbird Lane” pilot on Friday, as it delivered the net’s best numbers in the timeslot this fall.

Preliminary Nielsen estimates show “Mockingbird,” Bryan Singer’s reimagining of “The Munsters,” averaging a 1.5 rating/5 share in adults 18-49 and 5.4 million viewers overall — placing second in key demos to ABC’s “Shark Tank” (1.8/6 in 18-49, 6.8 million viewers overall). The series, starring Portia de Rossi, Eddie Izzard and Jerry O’Connell, wasn’t picked up to series by the Peacock, but the net was able to recoup some of the expensive pilot’s costs by drawing good numbers on the Friday before Halloween.

“Mockingbird” also helped boost 9 p.m. drama “Grimm” to season highs (1.9/6 in 18-49, 6.0 million viewers overall) as NBC narrowly won the night in 18-49 and 25-54 over ABC and CBS.

Up against “Shark Tank” and “Mockingbird Lane,” Fox’s season premiere of “Kitchen Nightmares” settled for ho-hum numbers (0.9/3 in 18-49, 2.7 million viewers overall), down sharply from its year-ago bow on the night (1.6/6), which faced softer competition.

Also on Friday, ABC did OK with its country music news special “20/20: All Access Nashville with Katie Couric” (1.4/4 in 18-49, 5.5 million viewers overall), tying in 18-49 for the 9 o’clock hour with CBS’ “CSI: NY” (1.4/4 in 18-49, 10.0 million viewers overall), which dominated in total viewers.

It was a tight battle in the night’s 10 o’clock hour, with NBC’s “Dateline” (1.5/5 in 18-49, 4.5 million viewers overall) edging out CBS’ “Blue Bloods” (1.4/5 in 18-49, 10.8 million viewers overall) and ABC’s “20/20” (1.4/4 in 18-49, 5.8 million viewers overall) in 18-49. “Blue Bloods” pulled ahead in adults 25-54 (2.2/6) and won easily in total viewers.

The night will look different starting next week, as “Undercover Boss” replaces crime drama repeats at 8 p.m. on CBS. In the same hour, ABC will premiere sophomore laffer “Last Man Standing” along with newcomer “Malibu Country,” with “Shark Tank” moving to 9.
