But not by as much as you might think.

TNT’s Falling Skies on Sunday was down 29 percent from its premiere. About 4.2 million viewers tuned in, along with 1.9 million viewers in the adult demo. Considering the Skies debut was the most-watched new cable show this year (and took a fair amount of flack from readers), this is still a strong number. TNT says the show “is expected to settle in over the next couple of weeks as the series finds its regular fan base.” Meanwhile, the fourth-season premiere of Leverage garnered 3.4 million, which is up 10 percent from its premiere last year.
