TV Ratings: 'Big Bang' Returns Steady, 'Men' Moves Down, 'Last Resort' Opens Soft

CBS retains its Thursday demo dominance -- and sees a strong 10 p.m. debut for "Elementary" -- while ABC's "Grey's Anatomy" manages to grow from last season.

The Big Bang Theory made a strong return to the schedule on Thursday night, pulling a 4.8 rating with adults 18-49 according to fast affiliate numbers. That's just a tenth of a point shy of its last season opener. Two and a Half Men's move to Thursday saw it take an unsurprising 67 percent drop from Monday's 2011 premiere, the first broadcast with Ashton Kutcher raked in 10.3 rating in the demo. Men pulled a 3.5 adults 18-49 rating, much stronger than How to Be a Gentlemen performed in the timeslot last year, but the series' lowest-rated original to date.

Last Resort was off to a slow start at 8 p.m. on ABC. The series premiere earned a 2.2 adults 18-49 rating, up just a tenth of a point from last year's Charlie's Angels opener in the same slot. The return of Grey's Anatomy brought in a 4.3 adults rating, up five from last year's premiere, while Scandal opened to a 2.2 adults rating at 10 p.m., 10 percent higher than its spring debut in the timeslot. The network earned a 2.9 adults rating and 9.2 million viewers for the night.

Fox ended its X Factor auditions, down six percent from last week to a 3.2 adults rating. A new Glee, featuring the debut of Sarah Jessica Parker, saw a 14 percent drop to a 2.5 rating in the demo. The network averaged a 2.8 with 18-49-ers over the two-hour block and 7.6 million viewers.

Football preemptions in Cleveland and Baltimore mean NBC's showing will likely go down in finals, but as it stands, the final Saturday Night Live election special pulled a 1.7 rating with 18-49-ers. Up All Night earned a 1.8 with adults, The Office had a 2.4 and Parks and Recreation was on top with a 2.1 -- those are all double-digit gains over last week's non-skewed returns. Rock Center With Brian Williams posted a 1.2 rating in the demo, giving NBC an average  1.7 adults rating and 4.7 million viewers for the night.
