On a night that saw competition from Game 2 of the NBA Finals and the Season 3 finale of Game Of Thrones over on HBO, Falling Skies returned for its third season on Sunday with just over 4.2 million viewers. The two-hour season premiere of the Steven Spielberg produced sci-fi series was down from the 4.5 million who watched its Season 2 debut on June 17, 2012. Among Adults 18-49 the premiere garnered 1.9 million adults, which is about even with last season’s pull in the demo.

Falling Skies launched as basic cable’s No. 1 new series in adults 18-49 in 2011. Among adults 25-54, last night’s Falling Skies was watched by 2.1 million viewers.
