‘56 Days’ is a psychological thriller miniseries on Prime Video, loosely based on Catherine Ryan Howard’s novel. The show opens with a disturbing scene of a body in a bathtub, setting a gripping tone. The story unfolds across two timelines: the present day, focusing on a murder mystery involving a gruesome discovery, and the past, revealing the intense and tumultuous relationship between Ciara Wyse (Dove Cameron) and Oliver Kennedy (Avan Jogia). The series explores their toxic relationship, marked by lies, impulsive decisions, and escalating danger. The past timeline delves into their romantic entanglement, while the present investigates who is in the bathtub and what led to this point. The show features strong chemistry between leads, clever plot twists, and a pulsating electronic score that heightens suspense. Changes from the novel include a setting shift from Dublin to Boston and some thematic adjustments, though some elements feel forced. Critics note that ‘56 Days’ is engaging despite its melodramatic tendencies, with the series gradually revealing layers of deception and dark secrets, making it a binge-worthy watch for fans of psychological thrillers.
