UPDATE PM: Two of the Wednesday freshman dramas whose fate is yet to be decided went each up a tenth in the finals — NBC’s The Mysteries of Laura (1.4) and Fox’s The Red Band Society (1.0). Both are now up a tenth from last week. In the case of Laura, last night’s performance was off just a tenth from its time period premiere, so the series’ chances for a back episodic order look good. (The cop dramedy already received a pickup of three additional scripts.)

PREVIOUS: We’re in Week 4 of the season, and the deadlines for the networks to make back order decisions on their freshman series are coming up. Most of the strongest new series on the major nets, ABC’s How to Get Away With Murder and Black-ish and Fox’s Gotham, have already received back orders (Nothing yet from CBS on Scorpion and NCIS: New Orleans, but those pickups should be coming soon).

Stalker-season-1-episode-3For the rest, every airing is important as it informs the network’s pickup decisions. Three of these series were on last night, and neither moved the needle on their chances significantly but all held steady, which is good for newbies. NBC’s The Mysteries Of Laura (1.3 in adults 18-49), CBS’ Stalker (1.7) and Fox’s Red Band Society (0.9) all matched their ratings performances from last week.

The entire NBC drama lineup held steady. The Mysteries Of Laura (1.3, 8.5 million) was even both in adults 18-49 and total viewers and, four weeks into the season, has remained within 0.2 of its time slot premiere 18-49 rating — the only new drama this fall to do so. While skewing older than NBC’s other Wednesday dramas, Mysteries Of Laura remained the most watched NBC series on Wednesday. Also matching its demo rating from last week was Law & Order: SVU (1.7, 7.3 million), which built onto its lead-in by 31%. At 10 PM, Chicago Fire (1.6, 6.7 million) inched up by a tenth.

After an uptick last Wednesday that helped Black-ish seal a full-season order, the freshman comedy (2.5) gave back the gains, down 11% from last week. The whole 9-11 PM ABC lineup was down — -3% for Modern Family (3.3) and -13% for Nashville (1.3) — as the network preempted its 8-9 PM comedies for Halloween specials, Toy Story Of Terror (1.8, down 42% from last fall’s debut) and evergreen It’s The Great Pumpkin, Charlie Brown (2.1, down a tenth from last year.) ABC finished tied with CBS for No. 1 in adults 18-49 (2.1), while CBS was as the most watched network (9.3 million).

On CBS, Criminal Minds (2.4) edged Survivor (2.3) after the reality series slipped two tenths and the crime drama climbed a tenth from last week. Criminal Minds also was the most watched program of the night with 10.8 million. Fox’s Hell’s Kitchen (1.2) mirrored Survivor‘s decline, also off by two tenths from last week.

After opening its third season last week up 11% from the Season 2 premiere, the CW’s Arrow (0.8) dropped 20% in Week 2. It is expected to close some of the gap in time-shifted viewing.
