What BollyAI Thinks

Season 13 at 94% on Rotten Tomatoes confirmed the return to form after Season 12's relative dip. During this period the show surpassed The Adventures of Ozzie and Harriet to become the longest-running American live-action sitcom in history by season count. The show's quality had not followed the typical network sitcom decline curve - the creative record across 13 seasons was without meaningful precedent in the genre.
