5 Thriller shows you wouldn't regret watching next

You

You is an American psychological thriller series based on Caroline Kepnes’ novels, developed by Greg Berlanti and Sera Gamble. It follows Joe Goldberg, a seemingly mild-mannered bookstore manager with a taste for vintage novels—and murder. His idea of romance? Obsession, stalking, and a body count. Charming, right?

Season one drops us into New York, where Joe becomes infatuated with aspiring writer Beck. Season two whisks him off to Los Angeles with a fake name and a new fixation, chef Love Quinn, who might just be more unhinged than he is. Season three turns domestic, with Joe and Love raising their baby in suburbia. But his wandering eyes and murderous habits return. Season four flips the script in London, where Joe joins an elite friend group and gets tangled in a deadly whodunit. Finally, in season five, he’s back in New York, trying to be good. Spoiler: he’s still terrible.

If you binged Unspeakable Sins and loved the cocktail of lust, secrets, and chaos, You will feed your dark little heart. Both shows thrive on obsession, morally bankrupt love, and jaw-dropping betrayal. Like Unspeakable Sins, You peels back the curtain on toxic desire. And if Unspeakable Sins showed us anything, it’s that love—twisted, desperate love—can be the deadliest sin of all.

Apple Tree Yard

Apple Tree Yard is a sleek, simmering British psychological thriller that rips the lid off the idea of quiet, respectable womanhood. Based on Louise Doughty’s bestselling novel, the four-part BBC series follows Yvonne Carmichael (played by Emily Watson), a successful scientist with a picture-perfect life—or so it seems.

After a magnetic stranger (Ben Chaplin) seduces her at the House of Commons, Yvonne plunges headfirst into a feverish, high-stakes affair in broom closets, cafés, and private places. It’s reckless. It’s addictive. And, as in Unspeakable Sins, it’s not long before intimacy and secrecy turn into something far more sinister.

But this isn’t just a midlife crisis with lipstick stains. After being brutally assaulted by a colleague, Yvonne’s world begins to crack. She turns to her lover for comfort, and when she lets slip that she wants her assaulter to disappear, he takes her a little too literally. What follows is a murder, a courtroom battle, and a woman put on trial not just for a crime, but for her desires. Sound familiar? Unspeakable Sins fans will find the same twisted cocktail of lust, danger, and moral decay shaken to perfection here.

Both shows expose what happens when women chase freedom in a world built to shame them. Like Unspeakable Sins, Apple Tree Yard reminds us that secrets are never just secrets—they’re ticking time bombs.

Behind Her Eyes

Behind Her Eyes starts off like your typical messy-office-romance drama, but baby, by the end, it’s full-blown astral projection murder chess. This twisty six-part Netflix thriller, created by Steve Lightfoot and based on Sarah Pinborough’s novel, follows Louise (played by Simona Brown), a single mum who falls for her boss David (played by Tom Bateman). She somehow ends up getting weirdly close to his mysterious, porcelain-doll wife Adele (played by Eve Hewson). Big mistake.

What begins as a love triangle morphs into a supernatural spiderweb of lucid dreams, sinister diaries, and a dead body in a well. Adele isn’t Adele. David isn’t innocent. And Louise? She’s about to get played like a psychic fiddle by Rob (played by Robert Aramayo), a sweet-faced sociopath who turns astral projection into a weapon of obsession.

If Unspeakable Sins made your jaw drop, Behind Her Eyes will have it on the floor. Both shows twist desire into something toxic, where love is a mask and manipulation is foreplay. Like Unspeakable Sins, this series goes darker than you can imagine. So if you’re into secrets, betrayal, and mind-nerving endings, pull the curtains and press play.

The Gardener

The Gardener (Spanish: El jardinero) is a Spanish romantic thriller series on Netflix that echoes the morally murky, emotionally charged terrain of Unspeakable Sins. Created by Miguel Sáez Carral, the show follows China “La China” Jurado and her emotionally detached son Elmer. They run a gardening business in Pontevedra as a front for their contract-killing side hustle.

But things get spicy when Elmer—sweet, strange, and haunted—falls for their next target: a soft-spoken schoolteacher named Violeta. Cue chaos, longing, and a moral minefield. If you thought Unspeakable Sins was messy, The Gardener is messier, just quieter about it. Where the former gives you hot affairs and blackmail in high-rises, the latter whispers death between flower beds and broken men. So if you binged Unspeakable Sins in one night and immediately craved more layered sin, forbidden desire, and beautifully damaged people, The Gardener is waiting. And yes, he’s holding secateurs.

Obsession

This four-part British erotic thriller follows William, a surgeon who becomes entangled with his son’s fiancée, Anna. What begins as desire soon spirals into a destructive obsession. The result? Scorched careers, broken families, and zero return tickets to normalcy.

Unlike Unspeakable Sins, which feeds on twisted justice and covert violence, Obsession is all about the slow, elegant burn—seduction turned poison, intimacy turned madness. But what it shares with the former is the same thrill, intoxication, and the hefty price of desire gone wrong.
