It was another sad Monday ratings performance for NBC, which hit another season low on the night with all original programming. Chuck (1.3/4) was even with last week, tying its series low. But it also delivered NBC’s highest demo rating last night. The Event (1.1/3) was down 13% from its last original two weeks ago for a series low. And the relaunch of Law & Order: Los Angeles continues to sputter. In its second week since the series’ return last Monday, the Law & Order spinoff drew a 1.1/3, down a steep 27% from the two-hour midseason premiere last week. Such an underwhelming performance bodes well for David E. Kelley’s Harry’s Law, which did better in the slot earlier this midseason.

ABC’s Dancing With the Stars performance show (3.9/11) was down 13% from last week to rank as the lowest-rated spring performance telecast ever for the venerable reality franchise. In its special airing after Dancing, a new Cougar Town (2.3/6) was down 15% from its last original Feb. 2. Proving that comedy series do better in a block, even with a weaker lead-in, that last original followed a Modern Family repeat. The first of a slew of specials about the upcoming Royal Wedding, ABC News: William & Catherine: A Modern Fairytale, averaged a 1.7/4 at 10 PM.

CBS’ newly sold in syndication Hawaii Five-0 (2.6/7) was one of only two series on the Big 4 to post a ratings gain last night, up 4% in the demo from last week, as the procedural dominated the 10 PM hour with guest star Sean Combs. How I Met Your Mother (2.5/8) was down 7% from last week to tie its series low. Midseason comedy Mad Love (1.9/5) was flat, followed by a Two and Half Men rerun (2.0/5), which was down a tenth from its performance at 9:30 PM last week, and Mike & Molly (2.5/6), which was flat with its tryout in the tentpole 9 PM slot last week.

The farewell episode of Amber Tamblyn on Fox’s House (3.2/9) was even with the medical drama’s demo rating last week, while The Chicago Code (1.9/5) joined Hawaii Five-0 in the black ratings column, up 6% from last week.

The CW’s Monday lineup had a strong return after a month-and-a-half-long hiatus. 90210 (1.7 million, 1.0/3 in 18-34) was up 21% in total viewers and 43% in 18-34 from its last original Feb. 28. Gossip Girl (1.5 million, 1.0/3) was up 7% and 25%, respectively.
