Critics have noted the film's attempt to balance humor with emotional depth, though opinions vary on its success in doing so.

While 'A Family Affair' has been praised for its lead performances and the unique chemistry between Kidman and Efron, it has also faced criticism for its predictable plot and lack of depth in character development. Some reviewers have pointed out the film's reliance on clichés and have critiqued its handling of the age-gap romance trope. Despite these criticisms, the film has been noted for its entertainment value and the strong performances of its lead actors.

The making of 'A Family Affair' provided an opportunity for Kidman and Efron to revisit their on-screen partnership, enriching their performances with a history of past collaboration. Off-screen, their camaraderie translated into a comfortable and dynamic working environment, potentially paving the way for future projects together. The film's exploration of age-gap relationships also contributes to ongoing discussions in Hollywood about diversity in storytelling and character representation.
