Although I’ve tagged the film ‘feminist’ I’m not sure it is; the debates are well summarised on Bitchflicks. I think the film is an exceptionally ‘open’ (or writerly in Barthes’ terms) text and so what follows is my reading although I’m conscious that this is exceptionally personal (by that I mean, although all readings we make are ‘personal’, with open texts our understanding of the world is likely to have a greater impact on the reading).
As Megan Kearns points out, on the Bitchflicks site, the ‘cool girl’ speech that Amy makes is key:
“The cool girl. The cool girl is hot. Cool girl doesn’t get angry. … And she presents her mouth for fucking.”
This is accompanied by shots of women (chosen by Fincher) and so suggests women are complicit (which they are) in allowing the ‘cool girl’ trope to be exploited by men. However, men are more complicit because of patriarchy, and Fincher should at least have included men within the mise en scene for this speech. Spoiler alert: also, the use of rape by Amy (Pike) to frame a man is contentious however I read her psychopathology as being the result of being pressured to be the ‘perfect woman’ (which began with her parents cannibalising her life as Amazing Amy). So although her murder of controlling millionaire Desi Collins isn’t justifiable in moral terms, I felt it was the right thing for Amy to do in her circumstances (that is, in the plot of a film and not reality). Amy does what it takes to take control of her life in a patriarchal world and, as such, is a feminist character.
This is a femme fatale that destroys the man who falls for her without destroying herself; although that was her original intention.
Flynn’s work is also a brilliant takedown of the romance of marriage; the roles and games we play that are not sustainable. This brings us back to Fight Club (which was a very faithful adaptation of Chuck Palahniuk’s novel) which similarly excoriated 21st century, bourgeois existence and Gone Girl is Fincher’s best film since then. His ‘cool’ visual style is a perfect accompaniment for the soullessness of modern existence.
