NBC’s The Voice (1.6 demo rating, 8.67 million viewers) tripped up ABC’s two-hour Dancing with the Stars premiere (1.1, 8.45M) Monday night, by 45% in the demo and 220,000 total viewers.

The Dancing with the Stars: Athletes edition launch drew the biggest audience to ABC’s 8-10 PM time slot in nearly six months, but clocked the long-running dancing franchise’s series lows for a regular episode in both demo and total viewers.

Conversely, The Voice climbed a tenth compared to the previous Monday.

After which, the season finale of NBC’s Good Girls (0.9, 4.24M) hung on to last week’s numbers, outstripping ABC’s The Crossing (0.5, 3.80M) as well as CBS’ Elementary (0.6, 4.68M) season debut in the demo. Elementary took over in total viewers, though the season opener dropped 23% in that metric compared with last season’s opener, also sliding two-tenths in the demo.

Airing in the eye of the reality competition series brawl cost CBS’ Kevin Can Wait (0.8, 5.02M) and Superior Donuts (0.7, 4.14M), each off a tenth from last week’s demo tally, but Man with a Plan (0.8, 4.79M) stayed the course. A Big Bang Theory repeat (0.7, 4.16M) aired at 9:30 PM.

Fox’s Lucifer (0.6, 2.82M) tumbled a tenth in the teeth of the reality-TV skirmish to hit a series low. But 9 PM’s The Resident (0.8, 3.87M) was steady compared to last week.

CW’s Supergirl (0.5, 1.51M) jumped a tenth as singing and dancing were duking it out; “iZombie” (0.2, 720K) was steady if modest.

NBC (1.4, 7.20M) won Monday’ Big 4 derby in both metrics, taking all six primetime half hours in the demo. Dancing home ABC (0.9,6.90M) came in second. CBS (0.7, 4.58M) and Fox (0.7, 3.35M) tied for third place in the demo, while CBS took bronze in total viewers. The CW (0.3, 1.12M) followed.
