A real-life hero took on a Marvel mutant last week and it was a draw in head-to-head total delayed viewership. With Live + 3 numbers in now and a small uptick among the key demo, WGN America’s Harriet Tubman-featuring Season 2 premiere of Underground is in a dead heat with FX’s Legion.

Each show had 1.8 million sets of eyeballs watching them at 10 PM on March 8. Now, yes, Underground was having a debut and the Noah Hawley-created Legion was in its fifth week, but the comparison is compelling when you realize FX is available in 10 million more households than WGNA.

Despite having commercials that the Season 1 ad-free debut lacked, Underground’s second-season premiere drew 878,000 viewers in WGN America’s 25-54 target market. Debut-to-debut, that’s a 10% decline in the demo. Factoring in the ad-free vs. ad-playing element and the L+3 25-54 demo result comes close.

Up 64% over its Live+Same Day total viewership, Underground was down 22% from the delayed viewing results of its WGNA record-breaking Season 1 premiere on March 9 last year. Still, its Season 2 launch was pretty much on par in another categories, and was even with last year’s debut in the 18-49 demo with a 0.4 rating in L+SD.

Looking at its L+SD 25-54 numbers, Underground’s March 8 Anthony Hemingway-directed “Contraband” episode saw a 77% rise in L+3 results. In the same delayed-viewing metric, the 18-49 demo had 835,000 viewers, up 3% over the series premiere’s 814,000.

With Nielsen ratings still trickling in due to a power outage at the company’s primary domestic collection facility in Florida, we don’t have numbers for last night’s Week 2 of Season 2 of Underground.
