The CW has got to be feeling good about plans to merge all four of its DC Comics-inspired shows this fall. The four-part crossover kicked off Monday night to season highs for Supergirl.

In its first season on the network, Supergirl rose two-tenths of a point in the key demo to an average 1.1 rating among adults 18-49. That matches its premiere high. Among total viewers, the episode ranks as its most-watched on the CW with 3.5 million viewers. The network will try to repeat that live-plus-same day success with episodes of The Flash, Arrow and Legends of Tomorrow. (Lead-out Jane the Virgin was modestly improved with an average 0.5 rating in the key demo.)

Monday's big winner was NBC and The Voice. The singing competition, its season finale now in sight, held steady with a 2.0 rating in the key demo — broadcast's biggest score for the night. At 10 p.m., Timeless fetched a steady 1.1 rating among adults 18-49.

ABC aired special CMA Country Christmas to the tune of a 1.3 rating among adults 18-49 and 7.8 million viewers. That score, like Conviction's, is tentative on account of NFL preemptions.

On Fox, Gotham held steady with a 1.0 rating in the key demo, and Lucifer improved to a 1.2 rating. And on CBS, The Odd Couple was forced to go it alone in a sea of repeats. The series dipped to a 0.9 rating among adults 18-49.
