What goes up, must come down the song says and, after a soaring debut, Supergirl (2.2/7) took a big fall last night in its second week. On an otherwise pretty steady night on the Big 4, the CBS newbie fell 29% among adults 18-49 from its premiere of its October 26 premiere.

But there are a few things to consider before swallowing the Kryptonite.

One, unlike its hugely promoted opener, Supergirl did not have a big Big Bang Theory lead-in last night as it moved to the 8 PM slot. Secondly, The Voice (3.2/9) had superstar Rhinna for another week, which had an obvious draw of its own as the NBC competition show saw a 3% bop up in the demo last night to be the highest rated show on the Big 4. Thirdly, fellow superhero series and WBTVer Gotham (1.6/5) had a 7% uptick from last week’s double digit rise, potentially drawing from the same demo. Fourth, even with the decline from Week 1 to Week 2, which was a bit more than usual for a new show, Supergirl delivered CBS a 16% and 20% rise in the demo and total viewers from the Monday time slot comedies of last season. Fifth and finally, the tale of Superman’s cousin still managed to match 10 PM’s Blindspot (2.2/7), which was up 5%, as the top scripted show of the night. All of which means the Live+ 3 for Supergirl Week 2could divine deeper ratings meaning later this week.

Overall NBC won the night among the Big 4 and the CW with a 2.9/9 rating and 10.57 million viewers.

Of course, the highest rated and most watched show of the night on both broadcast and cable will undoubtedly turn out to be, as it was many a week, Monday Night Football. With a great 29-26 game between the Carolina Panthers and the Indianapolis Colts, ESPN’s flagship NFL show pulled in an 8.8 in metered market results last night. That’s basically steady with last week’s MNF MM results, with a dip of just 2%.

The game was also shown on ABC affiliates in Charlotte and Indianapolis, so the early numbers for ABC are likely inflated. As it is, Dancing With The Stars (2.0/6) is up 11% from its October 26 show. The 2-hour reality show was followed by the special Countdown To The CMA Awards (1.0/3), which was pumping up Wednesday’s ceremony.

Not only did the CW’s Crazy Ex-Girlfriend (0.3/1) and Jane The Virgin (0.4/1) both raise a tenth but they hit some highs. With viewership of 977,000 the freshman got its best audience yet while Jane‘s 1.085 million was a Season 2 high. Both Fox’s Minority Report (0.6/2) and CBS’ Scorpion (1.9/5) were even with last week’s shows. NCIS: LA (1.2/4) dipped 8% from its last original of October 19.
