Ratings: Grimm Hits One-Year High, Nikita Drops, Mockingbird Lane Middling

NBC’s Grimm had a very happy Halloween this Friday, rising 27 percent in the demo to hit a 1.9 — topping the night and delivering its second-highest rating ever, behind the year-ago series premiere.

In total audience, the sophomore spooker saw a 19 percent gain to 6 million total viewers, its largest draw since Nov. 4, 2011.

Leading into Grimm, NBC’s Mockingbird Lane pilot-turned-standalone special drew 5.4 mil and a 1.5, good enough for third place and marking the network’s highest rating in the Fridays-at-8 time slot in two years. (It also improved upon the last repeat to air in this space for NBC by more than 50 percent.) Will the Peacock reconsider and find the reboot a “Spot” on the schedule? Stay tuned!
