The Achilles Effect explores gender bias in the entertainment aimed at primary school boys, focusing on the dominant themes in children’s TV shows, toy advertising, movies, and books: gender stereotypes of both sexes, male dominance, negative portrayals of fathers, breaking of the mother/son bond, and the devaluing of femininity. It examines the gender messages sent by pop culture, provides strategies for countering these messages, and encourages discussion of a vitally important issue that is rarely talked about—the impact of gender stereotypes on boys.
