Netflix achieved a surprising success with the dramatized version of The Staircase, a documentary series about the case in which Michael Peterson was accused of murdering his wife Kathleen Peterson, originally released in 2018. Produced by HBO and coming to Netflix in December 2025, this 8-episode adaptation comprehensively addresses the ongoing fight for justice, legal ups and downs, and uncertainties regarding guilt. Months after its release, the series has climbed to 7th place in global charts and has begun attracting an increasing number of viewers, especially in the United States.

The original documentary version of The Staircase provided unique access to the defense team and the Peterson family, meticulously following the legal process for over 16 years. This successful documentary stands out among Netflix's strong true crime works, alongside the Monster anthology series. While Netflix's true crime offerings push boundaries with dramatized elements, they are balanced with documentary series that remain faithful to the facts.

Despite containing dramatized elements, The Staircase series has garnered widespread acclaim from both critics and audiences, surpassing the original documentary in critic and viewer ratings. Like its predecessor, this series adopts a measured and non-judgmental approach; it presents various theories regarding Kathleen Peterson's death without definitively determining guilt. As noted by Rotten Tomatoes, the series "brings a new perspective and texture to the mystery" and is supported by Colin Firth's standout performance.

Miniseries are ideal for those who prefer to consume content in small bites that leave a lasting aftertaste long after the credits roll. The true crime genre is significantly more successful than its peers in leaving such lasting impressions. Our societal interest in real-life mysteries shows no signs of waning, and The Staircase's success on the platform is the latest proof of this.
