Tuesday TV Ratings 4/13/21: Big Sky Returns with a New Low, Prodigal Son Returns Steady, Young Rock Ticks Up (UPDATED)

Preliminary Analysis: Following an eight-week break, a defeated 'Big Sky' (0.5/0.4) came back onto the scene in catastrophic shape. The ABC drama hit a new low at 9 for the first-half of its return, only to fall even further in its signature 10pm slot. Previously, the series had never gone below a 0.6 A18-49 rating, with this performance going roughly 30% below its final, pre-hiatus episode (0.66). 'Big Sky' had little lead-in help from 'Pooch Perfect' (0.4), with the dog program remaining in troubling territory, but that was also the same rating it had to lead out of in mid-February. Fox's dramas were fresh off month-long breaks, with 'The Resident' (0.5) down a notch and 'Prodigal Son' (0.4) relatively unchanged. On NBC, 'Young Rock' (0.6) got back a tenth as 'This Is Us' (0.7) lost one in the 9pm slot. In-between, 'Kenan' (0.4) and 'New Amsterdam' (0.4) were frozen at concerning levels. CBS had encores of 'NCIS' (0.4), 'FBI' (0.4), and 'FBI: Most Wanted' (0.3). 'The Flash' (0.3) held steady on the CW, but 'Supergirl' (0.1) fell by a few hundredths.

Finals Update: This Is Us (+0.1), Supergirl (+0.1) and the repeat of FBI: Most Wanted (+0.1) adjusted up.
