Could the protagonist have been female without significantly impacting the film as a whole? (for a film with a male protagonist) [why this matters]
Is there a female character with significant screen time who grows, changes, and/or learns something over the course of the story? (for an ensemble cast, or a film with a male protagonist) [why this matters]
NOTE: This is not a “review” of Blackhat! It is simply an examination of how well or how poorly it represents women. (A movie that represents women well can still be a terrible film; a movie that represents women poorly can still be a great film.) Read my review of Blackhat.
