I really liked her distinction between "strong" characters and characters with agency, which is a real problem (and for what it's worth, is more of a problem in movies than in games, because whatever else you can say about Lara Croft, she's always had agency.) Also hadn't thought much about the ways tokenism makes it nearly impossible to have your one female character be interesting.

As far as quantity vs. quality goes, one thing that occurs to me is that if you fix the quantity problem, the quality problem will start to take care of itself. At least in the case of ensembles and genre films--the lack of female protagonists is more complicated (although as you noted, making Ripley female undoubtedly improved Alien, even if she's a Strong Female Character). Make half of your superhero team female, and guess what: your story isn't going to work if half of the team are SFCs with nothing else interesting about them. Superhero films are maybe not the best example, because they're also full of Strong Male Characters, but, I don't know, think about putting a quota on, say, a heist film. Or really any ensemble cast--didn't the relationship between Bond and M become more interesting when they arbitrarily gave the role to Judi Dench? (Imagine Skyfall with Bernard Lee.)
