One night after getting sampled by more than 16 million viewers in its return to Fox for the first time in 14 years, sci-fi drama “The X-Files” debuted in its regular Monday timeslot and stood as the evening’s top-rated program in the key 18-49 demo. It also helped provide a nice lead-in to new drama “Lucifer,” which debuted with promising numbers despite tough competition that included ABC’s hot “The Bachelor” and the night’s most-watched show overall, CBS drama “Scorpion.”

According to preliminary estimates from Nielsen, “The X-Files” led off the night for Fox with a 3.2 rating/10 share in adults 18-49 and 9.7 million viewers overall. While it was down sharply as expected from its special Sunday premiere (6.1 in 18-49, 16.2 million viewers overall), which followed a highly rated NFL playoff game, the drama revival dominated its hour and the night. (Sunday’s “X-Files” return, by the way, is the television season’s No. 2-rated broadcast entertainment series in 18-49, behind only the 6.7 for Fox’s season premiere of “Empire.”)

Looking closer at the timeslot debut of “X-Files,” the 3.2 rating tops 32 of 33 original episodes of “Gotham” to air Mondays at 8 over the past season and a half on Fox, and there’s a chance “X-Files” could match “Gotham’s” series premiere (3.3) in the finals. It also did a 2.1/8 in adults 18-34 and a 4.0/10 in adults 25-54. Roughly 52% of its 18-49 and 25-54 audience was male, as it was Monday’s No. 1 program in both categories.

At 9 p.m., “Lucifer” opened with a hot 2.4/7 in 18-49 and 7.2 million viewers overall, placing first in its time period in 18-49 and standing as the night’s No. 2 show in the demo. It matches “Rosewood” as the highest-rated of eight Fox series launches this season (more than doubling “Minority Report” in the same hour last fall), and is the top-rated premiere on any network since the debut of CBS drama “Supergirl” last October. In a good sign, “Lucifer” held just about all of its audience from its first half-hour (2.5 in 18-49) to its second (2.4).

Relative to “X-Files” in the preceding hour, the drama starring Tom Ellis as the devil caught in a struggle of good-vs.-evil while battling crime in Los Angeles fared best among men 18-34 (1.6/6), holding onto 80% of its lead-in. “Lucifer” led its hour in all key male demos.

For the night, Fox finished No. 1 in adults 18-49 (2.8/8) and 25-54 (3.5/9) and tied with ABC for first in 18-34 (1.8/7).

Elsewhere, ABC’s “The Bachelor” (2.3/7 in 18-49, 7.7 million viewers overall) edged up a tick from last week to hit a season high; it led its time period in adults 18-34 (2.2/8) and dominated in female demos. The net is still not getting much production out of its series of “Bachelor Live” post-shows (1.0/3 in 18-49, 4.0 million viewers overall), though it is preliminarily up a tick from last week.

CBS “Supergirl” (1.8/5 in 18-49, 8.0 million viewers overall) held up well opposite “X-Files,” matching last week’s score, while “Scorpion” (1.8/5 in 18-49, 10.6 million viewers overall) and “NCIS: Los Angeles” (1.5/5 in 18-49, 9.9 million viewers overall) cooled slightly from their strong showings of last week. “Scorpion” was again Monday’s top draw in total viewers, and the net placed first on the night by this measure.

NBC’s “Superstore” fell off a bit (1.4/5 in 18-49, 4.5 million viewers overall), down 0.3 from last week opposite all-original competition, including the arrival of “The X-Files.” It was followed by “Telenovela” (0.9/3 in 18-49, 3.3 million viewers overall), down 0.2, and “The Biggest Loser” (1.2/4 in 18-49, 3.6 million viewers overall), which rallied 0.2 to match its top score in four airings this month.

And at CW, the return of “Crazy Ex-Girlfriend” (0.3/1 in 18-49, 0.9 million viewers overall) and “Jane the Virgin” (0.4/1 in 18-49, 1.0 million viewers overall) were in line with prior results. “Crazy” had hit an un-rounded high with its final original of fall on Nov. 30 (0.34), and its star Rachel Bloom went on to win best actress in a comedy at both the Golden Globes and Critic Choice Awards.
