Billed as a family film, “The Princess Diaries 2” hits that mark by excluding most questionable content. However, the film deals with more mature issues than its predecessor. In addition to confronting the pressures of high-school popularity, Mia toys with love, marriage and national leadership, often handling these responsibilities inappropriately. The only truly disturbing moment in this film is a positive reference to homosexuality. While brief and not significant enough to warrant a negative acceptability rating, the reference reminds us that many filmmakers are targeting our children in subtle ways.
