The TV ratings for Sunday, October 11th are in; here are some of the highlights:

• At 8 p.m., Once Upon a Time on ABC notched a 1.6 rating in the key 18-49 demographic, and pulled 5.22 million viewers. Unfortunately for new series Blood and Oil though, those fair numbers on a very low night across the board didn’t hold at 9 p.m., where that series dropped almost a half point to a 0.8 rating and 3.82 million viewers.

• At 10 p.m., ABC’s Quantico notched a decent 1.6 rating and 5.67 million viewers; and though it tied for the highest scripted rating of the night on broadcast, everything (including NFL football) took a hit thanks to The Walking Dead’s return on AMC.

• 

  Still, football did a good turn for NBC (despite competing against the MLB playoffs), and a CBS football overrun means its scripted numbers are from in-between timeslots, and probably higher than they should be (although they do see in-line with recent ratings). So far, Madam Secretary at 8:33 p.m. pulled a 1.4 rating and 10.93 million viewers, with The Good Wife at 9:33 p.m. grabbing a 1.1 rating and 8.46 million viewers. CSI: Cyber finished the night for Eye with a 0.9 rating and 6.2 million viewers.

• On Fox, The Simpsons was down to a 1.5 rating and 3.29 million viewers at 8 p.m., and Brooklyn Nine-Nine dropped to a 1.3 rating and 2.73 million viewers. The Last Man on Earth stayed small and steady with a 1.1 rating and 2.67 million viewers at 9:30 p.m.

• As for the night’s curve-breaker, the ratings for The Walking Dead should be out later today or early tomorrow.
