Tuesday TV Ratings 5/4/21: Young Rock Finale Steady, NCIS and Prodigal Son Rise, Big Sky Hits Low After Renewal (UPDATED)

Preliminary Analysis: After falling to an egregious new low, 'NCIS' (0.8) enjoyed a nice rebound on CBS. The seasoned procedural gained two-tenths and returned to its position as the night's highest-rated broadcast. 'FBI' (0.7) held flat at 9 but 'FBI: Most Wanted' (0.6) gave back a tenth at 10. Fresh off of its renewal, ABC's 'Big Sky' (0.3) dropped to a new series low, airing after encores of 'Black-ish' (0.3) and 'Mixed-ish' (0.3). The freshman drama will need an upward adjustment to match or beat out its previous low (0.37). Earlier in the evening, 'Pooch Perfect' (0.4) held even at a poor number. On NBC, 'Young Rock' (0.5) matched last week's performance for its season one finale. 'New Amsterdam' (0.4) was also flat at 10, with the two originals separated by reruns of 'Young Rock' (0.4) and 'This Is Us' (0.3). Fox saw 'The Resident' post its fourth-straight 0.5 rating while 'Prodigal Son' (0.4) inched up. 'The Flash' (0.2) shed a tenth on the CW as 'Supergirl' (0.1) remained unchanged.

Finals Update: 'Big Sky' (+0.1), 'FBI' (+0.1), 'FBI: Most Wanted' (+0.1), and 'The Resident' (+0.1) adjusted up. This means that 'Big Sky' avoided hitting a new low by one-hundredth.
