After 56 days, detectives arrive at Oliver’s apartment to find an unidentified body that has been brutally murdered and intentionally decomposed. But the question remains: did Oliver kill Ciara or did she kill him?

The series is billed as a “unique crime story” and a “riveting, sexy, psychological thriller.”

What have TV critics said about the show?

The series has received mixed reviews from critics. Variety hailed the thriller as an “engaging series about revenge, secrets and the magic of electric chemistry,” noting that while some twists are obvious, the show “thrives because the audience never quite knows what to expect.”

However, not all reviews were positive. The Telegraph gave the “lifeless erotic thriller” just one star, commenting on the “cringeworthy dialogue.”

Meanwhile, The Irish Times said viewers expecting a “conventionally well-put-together mystery” will be underwhelmed, but those hoping for a “hysterically soapy thrill ride” won’t be disappointed.

56 Days is available to stream on Prime Video now.
