They may as well have named the movie “Strong Independent Girl.” Apparently because Disney hasn’t done enough damage to the intellectual development of three generations of American women, Pixar is introducing its much-ballyhooed first female lead, the princess Merinda, whom we are reliably informed is “more interested in archery and independence than in marrying and fulfilling royal traditions as dictated by her mother.” How innovative, how subversive, how not exactly the same as every other movie and television commercial produced in the last 20 years.
