After debuting to decent ratings last week, FX's mutant drama "Legion" has doubled its audience in Live +3 day ratings. According to Deadline, the premiere episode's ratings rose to 3.27 million viewers in delayed viewing and a 1.8 million in the 18-49 demo. That's a huge boost from the episode's 1.6 million live viewers and a measly 0.8 in the 18.-49 demographic.

However, as good a lift as those numbers may appear, it's still worth noting that the show's ratings still are far from ideal. In fact, "Legion" is still considered the least watched drama premiere for FX in recent years, with the since cancelled "Bastard Executioner," from "Sons of Anarchy" creator Kurt Sutter, and Tom Hardy's "Taboo" ahead of it. Of course, just because the premiere episode wasn't a huge ratings draw, that doesn't necessarily guarantee a cancellation. With "Legion" proving to be one of the best-rated comic book shows to date, it's entirely probable that the live viewership will see an uptick in coming weeks.

Created by Noah Hawley, “Legion” stars Dan Stevens, Rachel Keller, Jean Smart and Aubrey Plaza. The series is based on the character created by Chris Claremont and Bill Sienkiewicz, who first appeared in 1985’s New Mutants #25.
