Dark is surprisingly difficult to review without spoilers. Almost anything meaningful you say risks revealing a thread that the series very carefully wants you to pull yourself. For that reason, I will limit myself to the setup established in the first few episodes, and then step back to discuss the series in more abstract terms—what it does well, why it works, and how it compares to other stories dealing with time travel.
The series is set in the small German town of Winden, a place that appears entirely unremarkable at first glance. Its only distinguishing feature is a nearby nuclear power plant—an industrial presence that looms quietly over the town and its inhabitants. The story initially follows Jonas Kahnwald, a troubled teenager dealing with the recent suicide of his father, who leaves behind a mysterious letter that Jonas is explicitly instructed not to open until a specific time.
Shortly thereafter, Mikkel Nielsen—the younger brother of one of Jonas’s friends and romantic interests—goes missing. The search for Mikkel begins in the present day, but it quickly becomes clear that this is not a conventional missing-child story. Mikkel has somehow ended up in 1986, and from that point on, Dark begins to unfold into something far more complex.
That is as far as it is safe to go in terms of concrete plot. What follows over the course of three tightly structured seasons is a story that continuously deepens its mystery while still managing to move forward. Each season builds toward a powerful climax, answers some questions, raises many others, and ends on a note that feels both shocking and earned. Crucially, the third and final season delivers an actual conclusion—something that is far rarer in television than it should be.
What makes Dark stand out is that it is a time-travel story that more or less makes sense—at least as much as time travel ever can. It establishes clear internal rules and, more importantly, respects them. The series does not treat time travel as a convenient narrative escape hatch, but as a system with consequences, constraints, and moral weight.
This is where many time-travel stories falter. They create paradoxes they cannot resolve, rely on vague hand-waving, or simply stop caring about consistency once the emotional beats have been delivered. Older examples like Lost, and more recent ones like Stranger Things, show how easily a strong mystery can collapse under the weight of its own unanswered questions. In contrast, Dark never feels like it is improvising its way out of trouble. Even when the story becomes extremely complex, it gives the impression of being carefully planned.
That planning matters, especially in a medium where satisfying endings are increasingly rare. Many television series suffer from unexpected success: what was conceived as a one-season story suddenly needs to stretch into five, and narrative coherence becomes a casualty. Others simply run out of ideas, or resort to retroactive changes that undermine earlier episodes. Dark avoids these pitfalls. It is not afraid to reveal that certain things were misunderstood or misrepresented earlier—but when it does so, it feels intentional rather than desperate.
Change and reinterpretation are not problems in themselves. Stories can lie to the audience, or allow characters to lie to each other, as long as those lies are revealed in a way that feels honest. Dark excels at this. Looking back, there is often subtle foreshadowing—details that only make sense in hindsight, and which reward attentive viewers without requiring encyclopedic note-taking.
In the end, Dark is not just a strong time-travel story; it is a rare example of one that knows where it is going and commits to getting there. It is dense, demanding, and occasionally emotionally exhausting—but also deeply satisfying. In a genre littered with half-finished ideas and unresolved paradoxes, Dark stands out as something carefully constructed, rigorously thought through, and confidently brought to a close.
