What makes a work feminist? It's worth answering that before we begin. In some circles, depicting strong female characters resisting sexism is feminist. That's not enough for me. To qualify as a feminist work, I think that something actively needs to include an anti-oppression message, not just an anti-sexist one. A feminist work is one that challenges beliefs and attitudes about race, culture, gender, sexuality, disability, and much, much more. Not necessarily all in the same work or all at the same time, mind you, but I don't give a passing grade to works that are anti-sexist while conveying other -isms.
Your mileage may vary, and for the purposes of these evaluations, I'm looking at work that is considered feminist by society in general, not necessarily by my own standards, which means that these works might not pass my own personal litmus test. Or yours!
