Ratings: Big Finish for Criminal Minds' Prentiss

Paget Brewster’s Criminal Minds going-away party was well-attended, as the CBS crime drama this Wednesday delivered 13.7 million total viewers and a 3.6 demo rating, matching its most recent outing.

The mothership’s solid performance paved the way for CM: Suspect Behavior to register double-digit gains, rising to 10.35 million viewers and a 2.6 rating.

Elsewhere this Wednesday:

* American Idol‘s two-hour sing-off averaged 22.2 million viewers and a 7.4 rating, dipping 7 percent week-to-week.

* In the 8 o’clock hour, Survivor (10.6 mil/3.2) showed little movement, while Top Model sank to barely 2 million viewers and a series-low 0.9 rating. This, folks is why Tyra’s show is moving back an hour, to 9 pm, starting in mid-April.

* The forecast for Mr. Sunshine (joke never gets old) this week was “partly successful,” in that it didn’t lose any more viewers, but held steady at 4.6 mil and a 1.8 rating. The CW’s Shedding for the Wedding, meanwhile, shed (again, timeless!) more of the 18-49 crowd, offering up a gasp-worthy 0.4 rating.

* Opposite Criminal Minds 2 and an SVU repeat, ABC bubble show Off the Map was on par with last week, drawing 4.23 million viewers and a third place-worthy 1.4 demo rating.
