>Remember all of those scenes in movies from the 70s and earlier when halfway through the rape, the woman starts to get into it, and when we cut to the morning after and she's like "never leave me," and now the viewer is expected to sympathise with the rapist and his victim against the world?

Actually, no. I've seen plenty of old movies, but I don't recall many rape scenes, much less such rape scenes where the rapist is meant to be sympathized with, or where the rape victim takes pleasure in it.
