In a sea of streaming options, Cassandra rises above the noise. This German-language thriller on Netflix is an atmospheric blend of sci-fi, horror and family drama that will keep you on edge from start to finish.

The Prill family moves into a decaying house, looking for a fresh start, only to uncover a sinister secret, a robot named Cassandra, designed to assist with household chores. At first, she’s the perfect helper, but soon she turns into something far more dangerous, targeting Samira, the mother, in a chilling battle for survival. What’s more terrifying is that no one believes Samira, not even her husband, David, who dismisses her fears as paranoia.

What sets Cassandra apart is its patient, slowly unfolding narrative. While the eerie premise grips you, it’s the complex themes of control, identity and female rage that leave a lasting impact. The show delves into the tragic history of the house and the twisted connection between the robot and the real woman she’s based on, building tension as Samira uncovers dark truths about the past.

The pacing is deliberate, giving space to the characters to reflect, making each quiet moment feel loaded with suspense. This careful balance between building tension and character depth ensures you’re never rushing toward the climax – you’re living in it.

The performances are top-notch. Mina Tander brings empathy and depth to Samira, while Michael Klammer’s portrayal of David is complex and layered. But it’s Lavinia Wilson’s dual role as Cassandra that truly captivates. Her chilling presence as the robot is cold and calculating, and her portrayal of the human Cassandra is a haunting exploration of despair and madness.

Visually, the series is stunning, with a retro aesthetic that echoes the 1970s, adding to the unsettling atmosphere. The decaying house feels like a character in itself, holding dark secrets at every turn. The score enhances this unease, pulling you deeper into the story.

Cassandra proves itself a hidden gem. It’s not your typical fast-paced thriller – it’s a slow burn, but for those who embrace its methodical tension, the payoff is gripping and thought-provoking. If you’re after a series that lingers long after the credits roll, Cassandra is well worth the watch.
