Locke & Key has everything going for it on paper. Joe Hill and Gabriel Rodriguez’s comic series is one of the best horror-fantasy works of the past two decades, and the premise of a family discovering magical keys in their ancestral home is endlessly generative. The Netflix adaptation captures enough of that magic to keep viewers watching across three seasons, but it never quite reaches the heights the source material suggests are possible.
The show follows the Locke family after the murder of their father sends them to Keyhouse, an ancestral mansion in the small town of Matheson, Massachusetts. The children, Tyler, Kinsey, and Bode, discover that the house contains magical keys, each with a unique and often spectacular power. They also discover that a malevolent entity named Dodge wants those keys for far more dangerous purposes.
The Keys to Wonder
The magical key concept is genuinely brilliant, and the show’s best moments come from exploring what each key can do. The Head Key, which allows you to literally enter someone’s mind and remove or add memories and emotions, creates some of the series’ most visually inventive and emotionally resonant sequences. The Anywhere Key, the Ghost Key, and other discoveries throughout the run each introduce fresh possibilities that keep the mystery compelling.
The younger cast members bring an appealing energy to their roles. Connor Jessup, Emilia Jones, and Jackson Robert Scott work well together as siblings, and their excitement at discovering each new key captures a sense of childhood wonder that grounds the show’s supernatural elements in recognizable emotion.
The show’s production values are consistently strong for a Netflix genre series. Keyhouse itself is a terrific location, a sprawling New England mansion with enough character to feel like a member of the cast. The visual effects for the various key powers range from effective to impressive, and the show generally handles its more fantastical sequences with confidence.
When the show focuses on the mystery of the keys and the family’s slow unraveling of Keyhouse’s history, it works. These elements have the propulsive, page-turning quality that made the comic so addictive.
The Frustration of Bad Decisions
Locke & Key’s most persistent and damaging problem is its characters’ decision-making. The Locke children, particularly in the first two seasons, make choices so inexplicably poor that they break the show’s internal logic. They discover magical keys of enormous power and treat them with a casualness that strains credibility. They fail to communicate basic information to each other at critical moments for no reason other than the plot requires it. They trust people they shouldn’t and dismiss obvious threats with a consistency that moves from frustrating to infuriating.
This problem is compounded by the show’s tone, which softens the source material’s horror elements considerably. The comic is genuinely dark, with real consequences for its characters’ mistakes. The Netflix version pulls its punches repeatedly, creating a sense that nothing truly bad can happen to the main characters regardless of how carelessly they behave. This reduces the stakes dramatically and makes Dodge, the central villain, feel less threatening than the premise demands.
The adult characters fare even worse. The show struggles to give the Locke mother, played by Darby Stanchfield, meaningful involvement in the supernatural storyline, sidelining her for long stretches despite her proximity to the action. The town of Matheson never develops the lived-in quality that would make the setting feel real, remaining a backdrop rather than a community.
The third season, which compresses what should be a full season of story into eight episodes, rushes to a conclusion that doesn’t do justice to the mythology the show spent two seasons building.
Magic Without Consequences
The fundamental disconnect in Locke & Key is between the power of its concept and the weight of its execution. The keys represent enormous power, the ability to reshape minds, bodies, and reality itself, but the show rarely grapples with the moral and psychological implications of that power. In the comic, the keys exact a genuine toll on the people who use them. In the show, they’re treated more like fun gadgets than dangerous artifacts.
This lack of consequence undermines everything else. Horror without real danger isn’t scary. Mystery without real stakes isn’t tense. Locke & Key gestures toward depth without committing to it.
Should You Watch Locke & Key?
If you enjoy supernatural family adventures with a horror-lite tone, Locke & Key provides enough imaginative key concepts and appealing performances to justify a watch, particularly for younger teen audiences. The premise is strong enough to carry the show through its weaker stretches. Skip it if you’ve read the comic and expect the same level of darkness and consequence, or if characters making inexplicable decisions is a deal-breaker for you. Read the comic instead if you can.
The Verdict on Locke & Key
Locke & Key is a show that constantly falls short of its own potential. The key mythology is inventive, the young cast is likable, and the premise is one of the strongest in recent fantasy television. But the show’s reluctance to commit to real consequences, combined with character writing that too often prioritizes plot convenience over logic, keeps it from becoming what it should have been. It’s a pleasant enough watch that leaves you thinking about the great show hiding inside it.
