FX’s “Louie” has never been much of a ratings draw, but it returned from a lengthy break Monday by delivering better-than-average numbers for its fourth-season premiere.

Nielsen estimates that the 10 p.m. episode of “Louie,” the first episode of the critical fave since September 2012, averaged 941,000 viewers at 10 p.m., building on its lead-in from the movie “Horrible Bosses” (809,000). A second episode at 10:30 p.m. drew 910,000.

It was down from its season-three premiere in June 2012 (1.43 million), but that came on the same night as the much-anticipated return to television of Charlie Sheen in “Anger Management.” Compared to its most recent season average (791,000), though, the Louis C.K. series was up 19%.

“Louie” was also up 26% in adults 18-49 from its third season (635,000 vs. 505,000). The second episode on Monday edged up in the demo to 651,000.

In 18-49 rating for the 10 p.m. hour (0.5), FX ranked sixth among cable networks — behind TNT (NBA Playoffs), USA, VH1, Adult Swim and MTV.
