We may be heading into the holiday but things were sure moving around a lot on primetime last night. Slipping below a 2.0 for the very first time, freshman NBC hit Blindspot (1.9/6) had a 10% decline from last week. That’s a low in fast nationals for the thriller in its first fall finale. The Martin Gero created drama, which returns on February 29 next year, wasn’t helped by lead-in The Voice (2.5/8). While the top rated show of the night, the 2-hour live performance show took a 17% fall among adults 18-49 to hit its own low for this season, a Monday low that is.

Buffalo Bills v New England PatriotsWhile NBC topped the Big 4 and the CW for Monday in the demo with a 2.3/7 rating, the real winner of the night was the New England Patriots and Monday Night Football. The 10-0 still undefeated Super Bowl champs took down the Buffalo Bills 20-13 and the ESPN NFL flagship show earned a season high touchdown of a 10.0 metered market rating. Last night’s game, which will top cable and broadcast, was less than a yard ahead of the previous MNF record this year of the 9.9 MM rating of the October 5 game between the Detroit Lions and the Seattle Seahawks. It was, however, up a solid 16% over the November 16 Houston Texans’ win over the previously undefeated Cincinnati Bengals.

With ABC affiliates in Boston and Buffalo playing the game last night, ABC’s fast nationals are tentative and will undoubtedly see adjustments later. As it is, the first part of this season’s Dancing With The Stars (2.4/7) finale and Castle (1.5/5) are up significantly over their November 16 shows.

The same cannot be said for CBS’ Supergirl (1.5/5).

After steaming the downward ratings flow last week, the 8 PM superhero show took a 17% fall in the key demo. Like fellow newbie Blindspot, that’s a fast nationals low for Supergirl. Fellow superhero series, time slow rival and WBTV produced Gotham (1.4/4) was also down but just 7% and that could rise in the final numbers as it did last week for the Batman backstory show. Fox’s other offering of Monday night, Minority Report (0.6/2) was also down but a much harder 14%. CBS’ other shows of the night Scorpion (1.7/5) and NCIS: Los Angeles (1.2/4) were even and dipping 8% respectively.

Coming off a high last week, the CW’s Jane The Virgin (0.4/1) saw a 20% drop last night while lead-in Crazy Ex-Girlfriend (0.3/1) stayed the same as its November 16 show.
