It was a rough night for the broadcast networks. Ahead of the Easter and Passover holidays, Thursday brought season lows for a slew of series — including several dramatic drops.

CBS' The Big Bang Theory, averaging a 3.2 rating among adults 18-49, lost a whopping 1.2 ratings points (27 percent) from its most recent score. The Odd Couple (1.9 adults) fell six-tenths of a point just after. Mom (2.0 adults), comparatively steady, only lost two-tenths of a point. Elementary (1.2 adults) was off by the same measure.

Grey's Anatomy dropped four-tenths of a point to a series low 1.8 rating among adults 18-49 on ABC, while Scandal (2.1 adults) and American Crime (1.1 adults) both fell two-tenths to season lows.

Dateline (1.3 adults) grew three-tenths of a point before a steady Blacklist (1.6 adults), still at a same day low. And, at 10 p.m., The Slap closed its quiet run with a 0.7 rating in the key demo.
