Fast National ratings for Thursday, May 28, 2015.

In their head-to-head hour, the third week of FOX's "Wayward Pines" topped NBC's "Aquarius" in the key demographic, but the premiere of the David Duchovny drama led overall. And that's the way the Thursday primetime race broke down as well, with NBC winning overall and FOX eking out a victory in the key demo.

The two-hour "Aquarius" premiere ended up at The Mulaney Line in the key demographic and, boding ill for NBC and for the drama's binging possibilities, the audience dropped with each half-hour.

"Wayward Pines," meanwhile, lost a chunk of overall viewership from last week, but was flat week-to-week in the key demo.

And, of course, Thursday's top show was actually a repeat of "The Big Bang Theory."

Let's get to the numbers...

Among adults 18-49, FOX averaged a 1.2 rating for Thursday night, edging out the 1.1 rating for NBC and the 1.0 rating for CBS in the key demographic. ABC was a close third with a 0.9 key demo rating, followed at a distance by The CW's 0.2 key demo rating for the night.
