The show's ratings decline is popularly attributed to Episode #14 of Season 3, "I Am Curious… Maddie", which infamously had Maddie and David consummate their relationship after two and a half years of romantic tension. In commentaries on the third season DVD set, Caron disputed that the event led to the show's decline, but that a number of other factors led to the series' decline and eventual cancellation. In the fourth season, Willis and Shepherd had scant screen time together. Jay Daniel explained that: Bruce Willis was filming "Die Hard" during this period. When the film became a blockbuster, a film career beckoned and his desire to continue in a weekly series waned. In a series that depended on the chemistry between the two main stars, not having them together for the bulk of the fourth season hurt the ratings.
