Rush Hour S01E01 Still - H 2015

A returned Big Bang Theory won Thursday by all measures for CBS. With an average 3.4 rating among adults 18-49 and nearly 14 million viewers, the steady outing of the comedy helped keep most of the network's block in line — though the first episode of Rush Hour pulled an admittedly soft showing.

The dramedy's series premiere nabbed an average 1.1 rating among adults 18-49 and 5.1 million viewers. That's in line with the recent same-day time slot performance of Elementary, but pretty low by CBS standards. (See the recent 10 p.m. premiere of Criminal Minds: Beyond Borders, which is bringing a solid showing.) Rush Hour did not have the loftiest lead-in going for it. It was immediately preceded by an even 2 Broke Girls (1.6 adults), with back-to-back episodes of Life in Pieces (1.9 and 1.7 ratings) bridging the gap between Big Bang.

Fox won the night, however, with two hours of American Idol. Ahead of the franchise's impending swan song, it rose two-tenths of a point to an average 2.1 rating among adults 18-49 and an average 9 million viewers.

ABC also saw some lift. A steady Grey's Anatomy earned a 2.2 rating among adults 18-49 before Scandal (1.8 adults) improved by two-tenths of a point. The Catch saw no such boost. After a modest live-plus-three day lifts from the premiere, the second episode was off two-tenths of a point to a 1.0 rating among adults 18-49 and 5 million viewers. It ranked in last place during the 10 o'clock hour.

Shades of Blue signed off with a steady 1.1 rating among adults 18-49 for its season finale. That was after a Blacklist repeat and the conclusion of You, Me and the Apocalypse (0.6 adults).

Legends of Tomorrow (0.7 adults) and The 100 (0.5 adults) held steady on the CW.
