Honestly enough superheroes in movies, as a wife I'm way too tired of seeing 2-3 every year and also just stop the endless spidermen movies.
Don't. Care.
Give me a good story. I could care less if the hero is male or female, black or white. Just make a good movie dammit.
I agree with both of you (@MollyR, @joeblow9999). I thought the most compelling theme from the whole presentation was the concept of "Public Pedagogy" and the almost Kafkaesque way that the big media companies erase women superheroes from movie merchandising. Lets accept the premise that the motivation is to protect their investment in the manufactured identities created in genres targeted towards girls. All these characters are created so that we can identify with with them... its that affinity that makes us want to buy merchandise. Making a good movie dammit is probably not the priority (but it helps).
