A pair of femme-friendly cablers — Lifetime and ABC Family — got the New Year off to a strong start Monday.

Despite taking on ABC’s own lady magnet in “The Bachelor” as well as original episodes of CBS’ comedy block, Lifetime’s original movie “The Craigslist Killer” drew one of cable’s top movie demo scores in more than two years. And ABC Family’s second-year drama “Pretty Little Liars” hit series highs as it launched its winter season.

“Craigslist,” starring Jake McDorman and based on the real-life story of a 2009 Boston crime spree, averaged 2.72 million adults 25-54 and 5.39 million viewers overall, according to Nielsen — making it ad-supported cable’s No. 1 original movie in the 25-54 demo since TNT’s “The Librarian: Curse of the Judas Chalice” in December 2008. It’s also Lifetime’s fifth most-watched original movie ever, and its second most popular among adults 18-34 (1.7 million).

The net also scored after the movie with the hourlong doc “Beyond the Headlines: Catching the Craigslist Killer” (from CBS Eye Prods.), which drew 3.72 million viewers.

Over at ABC Family, “Pretty Little Liars” hit series highs, surging over its series-premiere deliveries from last June by 65% or more in total viewers (4.2 million vs. 2.5 million), 18-34 (1.4 million vs. 837,000), adults 18-49 (1.9 million vs. 1.1 million) and persons 12-34 (2.9 million vs. 1.7 million).

It also stacks up well historically for ABC Family, ranking among the top five telecasts ever in adults 18-34 and persons 12-34.

In its Monday 8-9 p.m. time-slot, “Liars” led all of television among femmes 12-34 (5.3 rating/15 share).

CBS led the broadcast pack Monday, garnering the best 18-49 score since September from “How I Met Your Mother” (3.9/11 in 18-49, 10.15m), and the best since November from “Rules of Engagement” (3.4/9, 9.76m), “Two and a Half Men” (4.7/12, 15.36m) and “Mike and Molly” (3.7/9, 12.39m).

ABC’s “The Bachelor” (2.9/7, 9.04m) came in below the demo delivery of its January 2010 bow (which didn’t face original CBS comedies).

ESPN’s coverage of college football’s Orange Bowl (Stanford-Virginia Tech) averaged a 3.6/9 in 18-49 and 10.68 million viewers overall.
