Alcatraz ended its first season on a very low note.

The drama's two-hour finale on Monday attracted 4.73 million viewers and a 1.5 in the adults 18-to-49 demographic — down 6 percent to mark a new series-low rating. The silver lining: Alcatraz maintained those numbers throughout the night.

Who should go home on Dancing with the Stars?

It was a down night overall, even with less competition with CBS airing repeats. Like last week, The Voice (11.8 million, 4.4) trumped Dancing with the Stars (17.6 million, 3.1) in the demo, but it was soundly beaten in terms of viewership. Both shows dropped in the demo as well: The Voice, down 4 percent for a season low; Dancing, 11 percent.

Up slightly in both measures, Castle (12.2 million, 2.4) took the 10 o'clock hour over Smash (6.36 million, 2.2), which remained flat at a season low.
