CBS ruled Tuesday from start to finish, as all three of its dramas once again topped their respective hours.

NCIS was the most-watched and top-rated show of the night with 18.5 million viewers and a 3.6 in the adults 18-to-49 demographic, falling slightly from last week. NCIS: Los Angeles (14.8 million, 3.1) and Vegas (12 million, 2.1) fell about 10 and 16 percent, respectively.

Fox's Raising Hope returned to 3.9 million viewers and a 1.7, well off of the 6.7 million and 3.1 it nabbed for its Season 2 opener, which followed New Girl's big debut last year. New Girl (5 million, 2.8) was flat, while Ben and Kate (3.2 million, 1.6) and The Mindy Project (3.7 million, 1.9) were both down more than 20 percent from their series premieres.

Vote: Which fall premieres won you over? Which flopped?

NBC opened its night with a Voice recap (8.2 million, 2.9), which led into the newly picked-up Go On (6 million, 2.2) and The New Normal (4.6 million, 1.7), both of which fell a couple tenths. Parenthood (4.4 million, 1.7) dropped just one-tenth from last week.

On ABC, Dancing with the Stars' results show (11.8 million, 2.1) was steady and Private Practice (6 million, 1.6) dropped three-tenths.

The season premiere of Hart of Dixie on The CW (1.5 million, 0.7) dipped slightly from its series premiere last fall.
