In spite of the NFC Championship football game running late on Fox on Sunday night (Jan. 24), the return of The X-Files was a huge success for the network, according to early ratings returns.

Being revived as a miniseries and premiering after the highly touted NFL matchup, The X-Files scored 13.5 million viewers in its debut, according to Forbes. The show’s big test will be tonight, as the second episode airs on Monday and the miniseries settles into its regular time slot for the rest of its six-episode run.

The X-Files’ viewership peaked in 1997, when the show brought in 27 million viewers for its fifth season premiere. Starring David Duchovny and Gillian Anderson, the franchise spawned two feature films: 1998’s The X-Files: Fight The Future and 2008’s The X-Files: I Want To Believe.

Fox’s last big series revival was 24: Live Another Day back in 2014. Roughly 8 million viewers tuned in to that miniseries’ premiere.
