I'd agree- there are a lot of sexual/female role/misogyny elements in your average horror thriller, including the classic "Women who have sex deserve to die" element.

Which is another reason that Pitch Black is interesting; there's definitely a sexual subtext between the male and female leaves, but it's incidental to the actual horror, and it's ultimately subverted at the end. Subverted twice, actually.

I could do a paper on the ways that Pitch Black screws with the horror genre, I really could.
