Prime Video recently released the mystery thriller series "56 Days", an adaptation of the novel by Irish author Catherine Ryan Howard. The show, produced by James Wan, follows detectives investigating a decomposed body found in a Boston apartment, while also chronicling the developing relationship between Ciara and Oliver in the 56 days leading up to the discovery. The series blends genres skillfully, with strong performances from the cast, but loses logic towards the finale as the writers overuse plot twists.

Why it matters

"56 Days" is an example of a TV series that provides a captivating, one-time viewing experience, but may not hold up to repeat viewings. The show's shift in setting from Dublin to Boston, as well as the introduction of Oliver's family wealth, alters the characters' motivations and the course of events compared to the original novel, which some fans may find jarring.

The details

"56 Days" follows a nonlinear structure, constantly shifting between passionate romance scenes, everyday moments, and the police investigation into the discovered body. Karla Souza and Dorian Missick excel as the well-coordinated detectives, while Dove Cameron and Avan Jogia deliver powerful performances in the lead roles. However, the closer the show gets to the finale, the more the writers rely on unbelievable plot twists that break the overall logic of the story.

  • The series is set 56 days before the discovery of a decomposed body in a Boston apartment.
