UPDATE 3 PM: As expected, given the 3-minute overrun, the premiere of the CW drama The Flash was adjusted up in the finals to a 1.9 in adults 18-49 and 4.8 million viewers to edge 90210 as the No.2 biggest debut ever on the network, only behind The Vampire Diaries. The Flash also outperformed several new series debuts on the Big 4 networks this fall in 18-49, dramas Forever (1.7), Red Band Society (1.3) and Gracepoint (1.2) and comedies Selfie (1.6), Manhattan Love Story (1.5), Bad Judge (1.3), A to Z (1.2) and Mulaney (1.0). It was only a tenth behind the openers of The Mysteries of Laura and Madam Secretary (2.0). Supernatural (1.1) was adjusted down a tenth.

ABC’s fast national ratings seem to have finally normalized, with only two one-tenth upward adjustments for Selfie (1.2) and Agents of S.H.I.E.L.D. (1.7). Also going up a tenth were NBC’s The Voice and Fox’s New Girl.

PREVIOUS: Here is why film studios and TV networks continue to flock to popular properties — the CW’s The Flash launched with 4.54 million viewers and a 1.8 rating among adults 18-49 last night, a numbers that would be considered solid for a Big 4 network. For the CW, this was the highest-rated premiere in five years, since The Vampire Diaries (also based on a well-known title), and the third-best series premiere in the network’s eight-year history. The Flash topped ABC’s comedies and Fox’s Family Guy rerun in the hour in 18-49 and total viewers and finished second in 18-34 (1.5).

The superhero drama bled into the 9 PM hour by three minutes, so its numbers will likely be adjusted up in the finals. It was followed by the season premiere of Supernatural (1.2) which is currently even with last fall’s opener but may be adjusted down. Still, the veteran is running head-to-head with Fox’s comedies in the 9 PM hour with a chance to edge them in the finals and helped the CW finish No. 3 for the night in both 18-49 and 18.34, ahead of ABC and Fox. This was the CW’s most-watched (3.7 million) and highest-rated in 18-49 (1.5) night in more than four years.

Selfie promo shotThose upward adjustments ABC has been getting this fall would come in handy for the network’s new comedies Selfie (1.1 fast national 18-49 rating) and Manhattan Love Story (0.9). As I’ve said before, expectations should be pretty low for the two comedies with no big stars and no lead-in, left to fend for themselves with no support in the Tuesday 8 PM hour. Still, those are some low numbers. Let’s keep in mind that the Selfie and Manhattan Love Story premieres were each adjusted up two tenths last week, so they may gain some ground. They’re currently running down 21% and 31%, respectively, from their openers. As part of Nielsen’s ongoing underreporting of ABC’s fast nationals, both Marvel’s Agents Of S.H.I.E.L.D. (1.6) and Forever (1.3) went up a tenth last week. They are currently down a tenth (S.H.I.E.L.D.) and flat (Forever) from last Tuesday’s fast nationals.

Whatever NCIS offshoot CBS decides to pair with the mothership series, it seems to fit like a glove. While NCIS: Los Angeles is struggling on Monday, the new NCIS spinoff that took its place behind the original series is doing great. NCIS: New Orleans (2.3, 15.3 million) matched its demo rating from last week with help from a visit from NCIS‘ Special Agent Gibbs (Mark Harmon), as did NCIS (2.6, 17.1 million), once again the night’s most-watched program. But Person Of Interest (1.6) was down 11% to a series low in Live+Same Day.

It was topped in the 10 PM hour by NBC’s Chicago Fire (2.1), down 9% from last week with a weaker lead-in as The Voice (2.4) aired a recap show vs. an original (4.1) last week. NBC barely edged CBS for the night in 18-49 (2.3 vs. 2.2) while CBS was clear No. 1 in total viewers with 14.1 million.

Fox improved slightly the 8 PM hour by subbing Utopia (0.8 last week) with a repeat of the Family Guy season premiere (0.9). New Girl (1.3) also was up a tenth from its fast national last week, The Mindy Project (1.0) was down a tenth.
