Ratings Chart Attack!

It was a slow Monday all around for the networks, and Fox, off the high of a successful “Terminator” run, struggled with its two new dramas, “New Amsterdam” and “Canterbury’s Law.”

CBS posted a 2.9 in the 18-49 age group, mainly with repeats, save for a pair of new episodes of “The New Adventures of Old Christine” (2.7, 3.3), up 14% from last week in the 9:30 showing. A repeat of “Two and a Half Men” (3.8) was the highest-rated show of the night.

Reality fare “My Dad Is Better Than Your Dad” (2.1) and “Deal or No Deal” (3.0) gave NBC second place with a 2.7. “Deal” was steady from last week, while “Dad” was down 13%. “Medium” (2.9) was on average.

ABC tied Fox with a 2.1. ABC rolled out a special recap episode of “The Bachelor,” in anticipation of its new season, to fair numbers (2.6). A two-hour episode of “October Road” clunked (1.8), landing around the back of the pack for each half-hour it was on.

Fox debuted “Canterbury’s Law” to low numbers (1.7), making it Fox’s lowest-rated regular-season premiere in that Monday time slot in at least 17 years.

“New Amsterdam” (2.5) moved into its official time slot yesterday. Without “American Idol” as a lead-in, “Amsterdam” dropped 29% from its previous airing. The show has dropped one full ratings point in each airing.

In fifth, The CW (0.6) aired a “Gossip Girl” repeat (0.5) and a new episode of “Pussycat Dolls Presents: Girlicious” (0.8, drawing a 1.0 in the 18-34 age group).
