Thursday TV Ratings 5/20/21: Last Man Standing Rises for Series Finale, Law & Order: SVU and Organized Crime Stable, Grey’s Anatomy Hits Series Low (UPDATED)

Preliminary Analysis: Amassing a total of 194 episodes and 9 seasons overall, Tim Allen sitcom 'Last Man Standing' (0.4) rose a tenth for its series finale. While serving as an improvement over the last three outings, this rating fell short of season-high territory and was lower than episodes from just a few months earlier. Although it'd have been foolish to expect 'Last Man' to soar into the 1.0 range for its last hurrah, it is disappointing that a program that aired for nearly a full decade would go out with such a whimper. Earlier in the night, Fox's puppet show 'Let's Be Real' (0.2) had a finale of its own, remaining steady at that pathetic number behind a 'Family Guy' encore. On ABC, 'Station 19' (0.7) lost a tenth while 'Grey's Anatomy' (0.8) shed a tenth-and-a-half. Canceled drama 'Rebel' (0.4) ticked up after having a repeat lead-in last week. Serving as the lone original on an island of reruns, CBS's 'United States of AI' (0.4) dropped by two-tenths and hit a new low. NBC was stable across the board with struggling 'Manifest' (0.4) and solid helpings of 'Law & Order: SVU' (0.7) and 'Organized Crime' (0.7). 'Walker' (0.2) gained a tenth on the CW as 'Legacies' (0.1) held even.

Finals Update: 'Station 19' (0.8, +0.1) and 'United States of Al '(0.5, +0.1) adjusted up.
