Two weeks ago, TBS’ “Ground Floor” posted a series high rating in the coveted adults 18-49 demographic. That momentum did not carry through to the two-part finale.

After dipping slightly for last week’s episode, “Ground Floor” returned to its titular location for the final show of the season. Thursday’s season one finale tied a series low 0.6 adults 18-49 rating. Its viewership average of 1.33 million was the third-lowest of the inaugural ten episode run.

Part one of the finale, which aired last week, posted a stronger 0.7 adults 18-49 rating with 1.59 million viewers. Its predecessor posted the series high 0.8 rating with 1.52 million viewers.
