Gugu Mbatha-Raw as Samantha Bloom, Boris Kodjoe as Steven Bloom in NBC's "Undercovers"

*NBC got some good news and bad news for two of its new dramas this week.

The network’s latest “Law & Order” franchise entry “Los Angeles” earned solid ratings in its Wednesday premiere, but numbers for the second week of spy series “Undercovers” slipped dangerously low, according to the Hollywood Reporter.

“Law & Order: Los Angeles” (10.6 million viewers) grew from its “Law & Order: SVU” (9.9 million) lead-in and clearly won 10 p.m., reports Nielsen. At 8 p.m., though, “Undercovers,” starring Boris Kodjoe and Gugu Mbatha-Raw, dropped 17% to 7.2 million.

“Undercovers” is prime time’s first drama to star two black actors in the lead roles. Kodjoe and Mbatha-Raw play married CIA operatives who take on sticky cases around the world while operating a catering business.

Most shows dropped off in viewers this week, and ABC’s “The Whole Truth” (4.6 million, down 5%) is firmly an at-risk show.

CBS won Wednesday with “Survivor” (12.2 million, down a bit), “Criminal Minds” (14.6 million, up a bit) and Week 2 of “The Defenders” (10.4 million, down 15%).

Fox’s two-hour “Hell’s Kitchen” averaged 6.1 million viewers, also down 15%.

ABC’s “Modern Family” (11.9 million) was down 6% from last week’s high-flying premiere, even with the heavily hyped “kiss episode.” The rest of its comedy block also fell: “The Middle” (8.4 million, down 5%), freshman comedy “Better With You” (7 million, down 11%), and “Cougar Town” (7 million, down 16%).
