Just the other day I was thinking about the lack of fearful lady antagonists in films and television. Off the top of my head I could think of two females that scared the shit out of me. Annie Wilkes in the Stephen King adapted film Misery and Amy Dunne in the Gillian Flynn adapted film Gone Girl.
By mere coincidence, the strangeness of the absence of the psycho female role came up again as I sat down to watch another book adapted into a movie. This time it was The Girl on the Train by Paula Hawkins.
This film engaged my attention all the way through. But the ending got me back to my original question. Why does Hollywood fear villainizing female characters?
