Why Josh Hartnett's Chilling Netflix Creature Thriller 'Below' Is Smashing Streaming Records

The Ultimate Spooky Season Binge Has Arrived on Netflix

If you have been hunting for a spine-tingling thriller to anchor your October binge list, Netflix just delivered the goods. Created and written by showrunner Jesse McKeown, the new six-episode limited series Below has quickly surged to the top of streaming charts worldwide. Blending coastal folk dread with visceral aquatic terror, the Canadian production offers the kind of atmospheric storytelling millennials grew up loving in classics like Jaws and The X-Files, while grounding its high-stakes drama in intimate family dysfunction.

Set against the unforgiving, fog-drenched shores of Snooks Arm in Newfoundland, the series stars Josh Hartnett as Calvin Penney, a weathered fisherman fighting both economic ruin and lingering personal ghosts. When abnormal deep-sea currents start washing up deformed seal carcasses and unsettling seismic tremors shake the harbour, Calvin soon realizes that an ancient, predatory creature has emerged from the cold Atlantic depths. Teaming up with his estranged son—portrayed with palpable anxiety by Charlie Heaton (fresh off his signature role in Stranger Things)—the duo must navigate paranoia, local skepticism, and a deadly menace that strikes from beneath the waves.

A Career-Best Renaissance for Josh Hartnett

Fresh off celebrated dramatic turns in Christopher Nolan's Oppenheimer and M. Night Shyamalan's psychological thriller Trap, Josh Hartnett cements his Hollywood resurgence here with raw emotional weight. Hartnett portrays Calvin not as an invincible action hero, but as a traumatized blue-collar father desperate to keep his family afloat while confronted by horrors beyond comprehension. His father-son dynamic with Heaton provides the emotional anchor of the miniseries, keeping the pacing tight across all six hour-long installments.

The supporting ensemble adds tremendous grit to the mystery. Mackenzie Davis (Station Eleven) plays a persistent marine biologist investigating ecological anomalies, while Willow Kean delivers a standout performance as Ruth, a village elder harboring forgotten folklore about what lurks on the ocean floor. Unlike standard CGI-heavy creature features, director Jesse McKeown relies on claustrophobic sound design, practical sets, and dreadful anticipation to keep viewers gripping their armrests.

Why 'Below' Is Winning Over Millennial Audiences

In an era oversaturated with formulaic true-crime documentaries, Below succeeds because it taps into genuine analog suspense. The series echoes the patient existential terror of Mike Flanagan's Midnight Mass while honoring the biological realism seen in Ridley Scott's The Terror. Viewers on social media have praised the climactic sunken house sequence in episode five, which critics have already hailed as one of the most inventive horror set-pieces of 2026.

Whether you are drawn to cosmic aquatic monster mysteries or compelling family drama, Below delivers a satisfying, self-contained journey that avoids cheap cliffhangers. All six episodes are currently streaming on Netflix—just be sure to keep the lights on when you hit play.
