Good movie but not in par with the book

Rating: 10/10 (18 December 2016)

The day of his fifth wedding anniversary, Nick Dunne returns home to find that his wife Amy is missing. Her disappearance receives heavy press coverage, as Amy was the inspiration for her parents' popular "Amazing Amy" children's books. Detective Rhonda Boney does a walkthrough of their house and finds poorly concealed evidence of a struggle. The police conduct a forensic analysis and uncover the remnants of cleaned blood stains, leading to the conclusion that Amy was murdered. Suspicions arise that Nick is responsible, and his apathetic behavior is interpreted by the media as characteristic of a sociopath.
Flashbacks reveal that Nick and Amy's marriage had disintegrated; both lost their jobs in the recession and moved from New York City to Nick's hometown of North Carthage, Missouri. Nick has become lazy, distant, uninterested and unfaithful. Boney unearths evidence of financial troubles and domestic disputes, and a witness states that Amy wanted to purchase a gun. She also finds a medical report indicating that Amy is pregnant, of which Nick denies knowledge, and a diary supposedly written by Amy highlighting her growing isolation, ominously ending with the fear that Nick will kill her.
