10 Underrated Netflix Thrillers You Can’t Afford to Miss
The Stranger (2020)
The Stranger is a British crime thriller based on the novel by Harlan Coben, and it’s one of those hidden gems that often gets overshadowed by its more popular counterparts. The story follows a grieving father, played by Richard Armitage, who receives a tip that his wife’s killer is still alive—and worse, he’s being protected by someone powerful. What unfolds is a gripping cat-and-mouse chase across the UK, filled with shocking twists and moral dilemmas.
What makes The Stranger stand out is its slow-burn approach to storytelling. Unlike many crime thrillers that rush from one explosion to the next, this series takes its time to build tension, making the payoff even more satisfying. The performances are top-notch, particularly Armitage’s portrayal of a man on the edge of sanity. If you love mysteries with real stakes and complex characters, this one is a must-watch.
Dark (2017–2020)
Okay, hear us out: Dark might not be entirely underrated in some circles, but it’s still criminally overlooked by mainstream audiences. This German sci-fi thriller is often compared to Stranger Things, but it’s a far more intricate and mature take on time travel, family secrets, and existential dread. Set in a small town where children begin disappearing, the show weaves a labyrinthine plot involving four interconnected families and a mystery that spans generations.
The beauty of Dark lies in its meticulous storytelling. Every detail matters, and the show rewards viewers who pay close attention. With its moody atmosphere, stellar acting, and mind-bending narrative, it’s a masterclass in suspense. If you enjoy shows that challenge you intellectually while keeping you on the edge of your seat, Dark is a must-binge.
Marianne (2019)
For fans of horror-thrillers, Marianne is a French gem that flew under the radar for too long. The story follows a bestselling author who receives a chilling letter from a character she created—a witch named Marianne who demands to be let out of the book. What starts as a darkly comedic horror premise quickly spirals into a terrifying descent into madness.
Marianne is a perfect blend of psychological horror and supernatural thriller, with a lead performance by Victoire Du Bois that’s both vulnerable and haunting. The show’s ability to balance scares with deep emotional stakes makes it a standout in the horror-thriller genre. If you’re looking for something that will keep you up at night, this French import is a must-watch.
The Chestnut Man (2021)
Another Scandinavian crime thriller, The Chestnut Man is based on the novel by Søren Sveistrup, the creator of The Killing. Set in Copenhagen, the series follows detectives Naia Thulin and Mark Hess as they hunt a serial killer who leaves behind a mysterious chestnut figurine at each crime scene. The killer’s motives are shrouded in mystery, and the investigation leads the detectives into a dark underworld of political corruption and personal demons.
What sets The Chestnut Man apart is its atmospheric tension and intricate plotting. The show doesn’t rely on cheap jump scares or over-the-top gore; instead, it builds suspense through its characters and the slow unraveling of the mystery. If you love Nordic noir, this is a series you won’t want to miss.
Between (2015–2016)
If you’re a fan of post-apocalyptic thrillers, Between is a hidden gem worth discovering. The series is set in a small town where a mysterious disease has killed everyone over 21, leaving the younger generation to fend for themselves. With no adults to guide them, the teens must navigate power struggles, love triangles, and a looming threat from the outside world.
Between is a unique take on the genre, blending survival drama with coming-of-age storytelling. While it doesn’t have the production value of big-budget apocalyptic shows, its raw, emotional core makes it a compelling watch. Plus, the mystery of the disease and its origins adds a layer of intrigue that keeps you hooked. If you’re looking for something different in the thriller space, this Canadian series is a great pick.
The Innocents (2018)
This Norwegian supernatural thriller is another example of why international thrillers often outshine their American counterparts. The Innocents follows a young couple, Iben and Erik, who get caught up in a supernatural mystery after their daughter begins exhibiting strange behavior. As they dig deeper, they uncover a dark family secret that threatens to consume them.
The show’s strength lies in its slow-burn approach and its ability to blend horror, drama, and thriller elements seamlessly. The performances are outstanding, and the eerie atmosphere will leave you questioning what’s real and what’s not. If you love shows like The OA or Dark, The Innocents is a must-watch.
The Spy (2019)
Based on the true story of Eli Cohen, an Israeli spy who infiltrated the Syrian government in the 1960s, The Spy is a gripping historical thriller that often gets lost in the shuffle of Netflix’s vast library. Sacha Baron Cohen delivers a powerhouse performance as Cohen, capturing both his cunning and his vulnerability as he navigates the dangerous world of espionage.
What makes The Spy stand out is its focus on the psychological toll of espionage. Unlike many spy thrillers that glorify the action, this series delves into the loneliness, fear, and moral ambiguity of living a double life. If you’re a fan of character-driven thrillers with real historical stakes, this is one you won’t want to miss.
The Woods (2020)
This Polish crime thriller is a slow-burn gem that rewards patience. The Woods follows a prosecutor, played by Michal Zurawski, who returns to his hometown to investigate a decades-old murder case. As he delves deeper into the past, he uncovers a web of corruption, betrayal, and family secrets that threaten to destroy him.
The show’s strength lies in its atmospheric tension and its focus on character development. Unlike many crime thrillers that rush to a conclusion, The Woods takes its time to build suspense, making the eventual revelations all the more satisfying. If you enjoy shows like True Detective or Mindhunter, this is a must-watch.
The Letter (2019)
For fans of psychological thrillers, The Letter is a South Korean gem that flew under the radar. The story follows a woman who receives a mysterious letter from her estranged sister, only to discover that her sister has been murdered. As she digs deeper into the mystery, she uncovers a dark family secret that threatens to consume her.
The Letter is a masterclass in suspense, with a tight script and outstanding performances. The show’s ability to balance mystery, drama, and psychological tension makes it a standout in the thriller genre. If you’re looking for something that will keep you guessing until the very end, this is a must-watch.
Parasyte: The Maxim (2014–2015)
Last but not least, Parasyte: The Maxim is a Japanese anime thriller that’s often overlooked by Western audiences. Based on the manga by Hitoshi Iwaaki, the series follows a teenager named Shinichi Izumi whose right hand is taken over by an alien parasite. Instead of killing him, the parasite, named Migi, forms a symbiotic relationship with Shinichi, leading to a series of thrilling and often disturbing adventures.
What makes Parasyte stand out is its blend of body horror, psychological thriller, and existential themes. The show doesn’t shy away from dark and challenging topics, making it a thought-provoking watch. If you’re a fan of anime or just looking for something unique in the thriller space, this is a must-watch.
Why These Underrated Thrillers Are Worth Your Time
At this point, you might be wondering: Why should I watch these underrated thrillers when there are so many other options out there? The answer lies in the unique experiences these shows offer. Here’s why they’re worth your time:
- Fresh Perspectives: Many of these thrillers come from international creators, offering storytelling styles and cultural perspectives that differ from mainstream Hollywood productions. This diversity enriches the thriller genre and keeps it from becoming stale.
- Tight, Intricate Plots: Unlike some mainstream thrillers that rely on shock value or predictable twists, these hidden gems often feature tighter, more intricate plots that reward close attention. You’ll find yourself rewatching scenes to catch hidden details.
- Strong Character Development: These shows prioritize character depth over cheap thrills. You’ll become deeply invested in the protagonists and antagonists, making the emotional stakes feel real.
- Atmospheric Tension: Many of these thrillers excel in creating an immersive atmosphere, whether it’s the eerie small-town setting of Dark, the claustrophobic tension of The Woods, or the supernatural dread of Marianne. The mood alone makes them worth watching.
- No Overused Tropes: If you’re tired of the same old “serial killer with a tragic backstory” or “love triangle in a dystopian future” tropes, these thrillers offer something completely different. They take risks with their storytelling and avoid clichés.
How to Find More Hidden Gems on Netflix
Now that you’ve got a list of underrated thrillers to dive into, you might be wondering how to find more hidden gems on Netflix. Here are a few tips to help you uncover the best-kept secrets in the platform’s library:
- Use Third-Party Aggregators: Websites like What’s On Netflix, FlixPatrol, and Flxtory track trending and underrated titles, often highlighting lesser-known gems before they go viral.
- Check International Sections: Netflix’s international libraries (e.g., Korean, French, Scandinavian, or Japanese) are treasure troves for underrated thrillers. Many of the shows on this list came from these regions, so don’t limit yourself to English-language content.
- Look for Low-Rated but Highly Praised Shows: Sometimes, shows with lower viewer ratings but strong critic reviews are overlooked by the algorithm. Check out Rotten Tomatoes or IMDb to see which hidden gems have high critic scores.
- Follow Niche Subreddits and Forums: Communities like r/NetflixBestOf, r/television, or genre-specific subreddits often share recommendations for underrated thrillers. Reddit users are great at uncovering hidden gems before they hit the mainstream.
- Turn Off Your “Recommended for You” Algorithm: Netflix’s algorithm tends to push popular titles, so if you want to find hidden gems, try browsing without logging in or use a VPN to access different regional libraries. Sometimes, the best shows aren’t what the algorithm thinks you’ll like.
- Check Award Lists: Shows that win or are nominated for international awards (e.g., International Emmy Awards) often fly under the radar but are critically acclaimed. Keep an eye on these lists for hidden gems.
Common Mistakes to Avoid When Binge-Watching Underrated Thrillers
While diving into these underrated thrillers can be incredibly rewarding, there are a few common mistakes to avoid to ensure you get the most out of your binge:
- Spoiling Yourself: Some of these shows have intricate plots with major twists. Avoid reading too many reviews or checking spoiler-filled forums before watching. Let the mystery unfold naturally.
- Watching in the Wrong Order: If a show has multiple seasons or is part of a larger franchise (e.g., Dark), make sure you’re watching them in the correct order. Skipping ahead can ruin the experience.
- Ignoring Subtitles: Many of these thrillers are non-English productions. While some may have dubs, the best experience often comes from watching with subtitles to catch nuances in dialogue and performance.
- Judging Too Soon: Some hidden gems take a few episodes to truly hit their stride. Give the show a fair chance before deciding whether it’s worth continuing.
- Not Taking Breaks: Thrillers are intense by nature, and binge-watching too much at once can lead to burnout. Take breaks between episodes or seasons to process what you’ve watched and avoid fatigue.
