Brilliant Joss Whedon quote, on the feminism and intended audience ("Is it for boys?" was the question) of Firefly/Serenity vs. Buffy:
There are more beautiful, kick ass women per square inch on this screen than I have ever had before. Because in Buffy, it was a concept that needed to be exploited and it’s in fact in the title. By the time you get to Serenity, it’s just accepted as part of both my lexicon and the world’s and to the world of the future.
Now that's a future world-view that I can get behind.
ETA: The rest of the interview is
here, and it's thematically but not storyline spoilery for Serenity.
