The typical TV audience ebb on a weeknight All Hallow’s Eve led to some spooky ratings drops for just about everyone. The entire broadcast schedule inched closer to total fractionality, with series lows abounding.

As a reminder, many of these shows will see ratings gains of at least 50% once viewership within three and seven days is tallied. (However, most of those viewers won’t count toward the deliveries networks guarantee advertisers.)

NBC’s “The Voice” hit a low with a 2.0 in the advertiser-coveted 18-49 demographic and 9.26 million viewers — yet such are these times that a rounded-up 2.0 demo rating was enough to win the night. “Timeless” followed with another drop, to a 1.1 in the demo (compared to a 1.6 in early ratings last week) and 5.88 million total viewers.

CBS’ “Kevin Can Wait,” which had dipped last week in early ratings to a 1.6 in the demo without its “Big Bang Theory” lead-in, fell again to a 1.4, with an audience of 6.76 million. Matt LeBlanc comedy “Man With a Plan” bested its lead-in with a 1.5 in the demo and 6.67 million viewers. “2 Broke Girls” drew a 1.5 as well, with 5.85 million viewers, and “The Odd Couple” finished the night’s comedy block with a 1.2 and 5.12 million viewers. A Halloween-themed episode of “Scorpion” built on that with a 1.4 and 7.14 million. (CBS’ lineup was preempted for football in Minneapolis, as the Vikings faced the Chicago Bears on “Monday Night Football.”)

ABC’s “Dancing With the Stars” weighed in with a 1.5 and 10.27 million viewers. “Conviction” had the night off in favor of a Country Music Association Awards-related special, “All Access Nashville: Celebrating the CMA Awards With Robin Roberts,” which brought in a 0.7 demo rating and 4.63 million viewers.

The CW’s “Supergirl” lost about a third of its demo audience from last week, dropping to a 0.6 and 2.2 million viewers. “Jane the Virgin” drew a 0.4 and 1.02 million viewers.

On Fox, “Gotham” pulled in a 0.9 and 3.05 million viewers, and “Lucifer,” which was just picked up for a full season, drew a 0.9 and 3.44 million viewers.
