Netflix has become a vast repository of sci-fi horror, offering a mix of classics and new releases. While blockbusters often dominate the spotlight, many compelling films fly under the radar. This list highlights some underrated sci-fi horror on Netflix that deserve your attention.
The Block Island Sound (2020): A Creeping Coastal Horror

This atmospheric thriller blends family drama with a chilling sci-fi mystery. While the film centers on a family’s internal struggles, a sinister, otherworldly presence lurks in the background, emanating from the ocean’s depths. “The Block Island Sound” masterfully builds tension and dread, culminating in unsettling revelations. As an indie production, it effectively tackles a genre typically reserved for big-budget films.
Oxygen (2021): Claustrophobic Terror in Real-Time

“Oxygen” presents a familiar premise: a trapped protagonist with amnesia struggling to escape. However, the film elevates this classic trope through a tightly paced narrative that expertly reveals information piece by piece. The confined setting and the protagonist’s desperate search for answers create a deeply claustrophobic and engaging experience.
Circle (2015): A Social Experiment Gone Wrong

Imagine waking up in a circle with strangers, facing imminent vaporization by an unseen force. “Circle” combines the alien abduction and “game of death” concepts into a chilling social experiment. The film’s static setting and tense atmosphere create a palpable sense of dread, immersing the viewer in the characters’ terrifying predicament.
ARQ (2016): Trapped in a Time Loop

“ARQ” throws viewers headfirst into a time loop narrative. While the initial rapid-fire storytelling may feel disorienting, the repeating cycle allows the pieces of the puzzle to fall into place. Set in a dystopian future with a polluted atmosphere and scarce resources, “ARQ” offers a unique and thought-provoking take on the time loop concept.
Underwater (2020): Deep-Sea Terror

Drawing comparisons to Ridley Scott’s “Alien,” “Underwater” delivers a thrilling deep-sea horror experience. When a catastrophic leak jeopardizes an underwater research facility, the surviving crew must confront a terrifying, unexpected threat. While not reaching the heights of its inspiration, “Underwater” delivers a suspenseful and visually impressive monster movie.
Europa Report (2013): Found Footage from Jupiter’s Moon

Inspired by the real-life discovery of water on Jupiter’s moon Europa, this found-footage film follows a mission to explore the potentially habitable celestial body. When the crew loses contact with Earth, the footage reveals a chilling and mysterious encounter. “Europa Report” blends realistic sci-fi elements with a classic horror structure, creating a unique and unsettling viewing experience.
