Josh Hartnett anchors Netflix’s pulse-pounding sea monster thriller Below: TV review

Show summary Hide summary

Netflix’s new limited series Below pulls viewers into a wind-swept Newfoundland community where the sea keeps its secrets. The show mixes mystery, family drama and environmental dread, centering on a man haunted by a childhood tragedy and a town that can’t agree on how to survive the changing ocean.

Plot snapshot: a small town, a drowned past, a rising threat

The story opens in 1986 with a traumatic accident that follows one family for decades. A young boy makes a choice in a storm that costs his father his life. Forty years later, that boy is a man trying to hold his community together.

Snook’s Arm: a once-bustling harbour now dotted with empty docks and guest rooms.

Snook’s Arm is shrinking. Fish hauls are rare. Locals scrape by delivering ice and running small guest rooms. When an eerie scent and strange behavior start appearing around the water, residents suspect more than rotten catches. A massive iceberg and a series of violent incidents push the town toward chaos.

Key players and standout performances

The drama is anchored by Josh Hartnett as Calvin Penney, the man at the story’s center. He’s a widower who wears grief quietly. His performance shows a man stubbornly clinging to home and memory.

  • Calvin Penney (Josh Hartnett) — haunted, practical, determined.
  • Wade (Charlie Heaton) — Calvin’s son, struggles with impulsive coping and addiction.
  • Dr. Fonda Howander (Mackenzie Davis) — the inquisitive scientist who questions the water.
  • Mary and Jay (Ruby Stokes, Rohan Campbell) — family members who return to help and to confront the past.
  • Ruth (Willow Kean) — the harbor master, practical and resilient.

Mackenzie Davis brings curiosity and moral clarity. Charlie Heaton and the younger cast add grit and urgency. Hartnett’s Newfoundland accent occasionally slips, but his emotional core holds the series together.

How the show blends horror, thriller, and climate commentary

Below uses a sea creature as a catalyst, but the real focus is human behavior. The monster drives the plot, yet the show is most interested in what people do when resources vanish and fear spreads.

  • Survival instincts vs. community care
  • Greed and opportunism exposed in small towns
  • Long-term effects of climate change on coastal life

The series treats environmental collapse as both backdrop and antagonist. The iceberg and fouled water are tangible threats. The social breakdown they trigger is the darker horror.

Episode structure and pace — why six episodes work

The limited run keeps momentum. Episodes are compact, usually under 45 minutes. The storytelling is tight, with a steady acceleration of tension.

One standout is Episode 4, which focuses on the creature and the price people pay for selfish choices. It reveals moral compromises and shocks the town into new extremes. The penultimate episode peels back more personal history, connecting the present danger to Calvin’s childhood.

Setting and atmosphere: Newfoundland as a character

The series frames Snook’s Arm as more than a backdrop. Fog, ice, and empty docks create a mood of isolation. The community’s traditions, like Come Home Year, show both resilience and the pain of loss.

Filmmaking leans on natural sound and cold palettes. The ocean feels both beautiful and merciless. That contrast amplifies the show’s themes about impermanence and the smallness of human plans.

Themes that make Below resonate on search and discovery

Below taps into cultural anxieties that perform well for search intent and news interest. Key themes include:

  • Climate change’s human cost — shrinking fisheries, ice drift, altered livelihoods.
  • Intergenerational trauma — how a single event reshapes family dynamics.
  • Community vs. individualism — who you save when resources run out.
  • Genre fusion — how horror and social drama combine to tell modern stories.

Why viewers might click and share

  • Star power: Josh Hartnett and Mackenzie Davis draw attention.
  • Short, bingeable run makes it easy to finish over a weekend.
  • Topical hooks: climate crisis, coastal communities, creature horror.

What critics and viewers should watch for

Pay close attention to the show’s exploration of moral choices. Episodes layer reveals about the Penney family. The series asks who pays for progress and who pays for survival.
