WARNING: This review contains plot spoilers
Gillian Flynn's best-selling novel Gone Girl always had the makings of a great trashy thriller, since the book itself was mostly an airport read- a potboiling page turner with plenty of twists, gore, mystery, and spoiler alert- a fantastic femme fatale, so villainous as to rival any of the women in a classic film noir. Yes, Amazing Amy herself is what really sold the book- she holds her husband and the audience in the palm of her hand, manipulating every word, action and event in what turns out to be her story from start to finish.
That doesn't necessarily mean that you're on her side though, and the book was told in equal part (at least during the first half) from Amy's dunce of a husband Nick's perspective, which lets us in on the reality of what's happening from that first, surreal day that Amy went missing. Amy and Nick Dunne were once a happily married couple who met in New York but moved to his hometown in Missouri when Nick's mother got sick and they both got laid off from their jobs as magazine writers. The blissful happiness they once shared then began to fall away bit by bit, as resentment, frustration, money problems, and eventually infidelity took a toll on the marriage, as it does with so many couples. The marital troubles should be recognizable to most, but this film only wants to skim the surface of what makes marriage viable or not for these two people, and the real heart of the story lies in the pulpy thriller material, which director David Fincher so excels at.
In a way, genre material like this is perfect for the meticulous technician, who draws comparison to Alfred Hitchcock in the way he controls his shots and actors, and who creates an effective atmosphere of dread that permeates every frame. That's all done as well here as it is in his best movies, which include Fight Club, Zodiac, The Social Network, and The Girl With the Dragon Tattoo. The first half of the movie follows the procedural aspects of the early days when Amy went missing, as we see the little Missouri town begin to turn on Nick as the prime suspect, due in no small part to the uninviting way he acts in the face of mass media scrutiny. This would require a tricky performance from Ben Affleck, as he needs to play a guy who's not that smart but also convey the shiftiness of a potential killer- we in the audience need to suspect him as much as the local cops do. He mostly pulls it off, although I've never seen a whole lot of range from him as an actor and that perception has not been changed by this movie. It may just be a case of his having been well cast, as he comes across as both a nice guy and kind of a jerk at different times in reality as well as on film.
