I especially liked the focus on how female stereotypes in media affect young girls' self-esteem and ultimately their chances of growing up to be leaders. Obviously the documentary was US- centric, but these problems exist pretty much all over the Western world, where girls see very few really good role-models in mainstream media and where the few that exist are always heavily scrutinized and criticized.
Since media has changed so much in the past 20 years, I agree with what was also said in the movie: That media literacy, the ability to understand media as products (created by humans with their own biases and agendas), has become almost as important as the ability to read. After all, these days it's pretty much impossible to shield children from harmful media messages, so it's vital that they have the tools to deal with those messages. This is true not just for girls, but also for boys.
