feminist films |
what % of the story is told from a female perspective?
what % of the main characters are female? how are the women portrayed? do they have power, choice or agency? how are women's relationships with other women? is there friendship or a sense of sisterhood? do the women work together or help each other? how are women's relationships with men? does the film raise issues of interest to women or feminists? does it go beyond the individual, and also give broader messages about society? |
