Thursday TV Ratings 9/16/21: Brooklyn Nine-Nine Series Finale Rises, Big Brother Stays on Top, When Nature Calls Finale and The Hustler Stay Low, The Outpost Rises After Cancellation (UPDATED)

Ratings Analysis: After over 150 episodes, countless timeslot changes, and a highly-publicized network swap, 'Brooklyn Nine-Nine' (0.39) closed out its run in rather quiet fashion on NBC. Although the series finale did pick up a tenth, the Samberg cop sitcom failed to hit a new season high for its final outing. Reruns of 'Law & Order: SVU' (0.23) and 'Organized Crime' (0.24) filled out the 9-11pm stretch. ABC's struggling newbie 'When Nature Calls' (0.20) held flat for its finale but lost nearly half of the 'Holey Moley' rerun (0.36) that preceded it. Though it remained in dire territory, 'The Hustler' (0.22) was able to build a bit from 'Nature' at 10. CBS's 'Big Brother' (0.94) gained a couple hundredths and led into a rerun of 'Bull' (0.20). Fox's encores of 'MasterChef' (0.29) and 'Call Me Kat' (0.25/0.22) bested ABC's original efforts. 'Coroner' (0.09) and recently-canceled drama 'The Outpost' (0.05) gained one-hundredth apiece on the CW.

Finals Update: The 'Brooklyn Nine-Nine' series finale (0.4, -0.1) and repeats of 'MasterChef' (0.3, -0.1), 'Call Me Kat' (0.3, -0.1; 0.2, -0.2), 'Law & Order: SVU' (0.2, -0.3), and 'Organized Crime' (0.2, -0.3) all adjusted down. The 'Holey Moley' rerun (0.4, +0.1) adjusted up.
