Update: The adults 18-49 number did not brighten the outlook for FOX’s “Rake.”

Squandering half its lead-in support in the coveted demo, Thursday’s “Rake” premiere drew a 1.7 adults 18-49 rating with 7.1 million viewers.

“Idol,” which led into “Rake,” posted a 3.4 with 12.1 million viewers.

FOX’s new dramedy failed to “Rake” in the viewers Thursday.

Leading out of “American Idol,” which drew an 8.0 overnight metered market rating in the 8PM timeslot, “Rake” posted a 4.5.

Unimpressive from a purely numerical standpoint, the performance is even more disappointing in context. Instead of dealing with original episodes of CBS’ 9PM comedies “The Crazy Ones” and “Two and a Half Men” and ABC’s “Grey’s Anatomy,” the “Rake” premiere only had to contend with CBS comedy encores and ABC’s low-rated “The Taste.”

Perception of the performance could be salvaged by a strong showing in the adults 18-49 demographic, but there is no presently no doubt that “Rake” did not arrive as any sort of hit.
