Shady Business is one of those miniseries that turns a seemingly local incident into a much bigger conflict. This British thriller, available on Movistar Plus+, begins with the discovery of thousands of dead fish in the rivers of a small Oxfordshire town and follows the investigation led by two retirees who refuse to accept the explanations offered by the water supply company.
Created by Joseph Bullman and featuring David Thewlis and Jason Watkins, the fiction has drawn a notably positive response from critics. At its launch, it boasted a 100% positive rating on Rotten Tomatoes, a figure that places it among the most striking catalogue options for those seeking a short, uncomfortable British drama based on real events.
What that 100% on Rotten Tomatoes really means
The figure can be striking, but it’s worth reading it correctly. Rotten Tomatoes’ 100% doesn’t mean that every critic gave the series its highest possible score, but that all of the reviews counted have been deemed positive by the aggregator’s system.
The distinction is important: a production can achieve a perfect percentage with reviews of varying intensity. Therefore, the appeal of Shady Business does not rely solely on a number, but on the recurring elements in the reviews: the direct tone of the storytelling, the balance between denunciation and entertainment, and the work of its two leads.
An environmental mystery that doesn’t need grand artifices
The series opens with an image hard to ignore: neighbours discover a large quantity of dead fish in the local waterways. The company responsible for the supply offers an explanation that not everyone finds convincing, and that becomes the true driver of the story.
Rather than relying on a conventional police investigation, the fiction places two retirees willing to ask questions at the centre. Their stance allows the narrative to advance from everyday observation and the community’s distrust, rather than from the authority of professional investigators or experts with privileged access to all information.
The conflict grows when the initial doubts point toward a web of negligence, questionable corporate decisions, and possible attempts to hide accountability. The series does not present environmental degradation as an abstract problem: it ties it to the people who live near the rivers and to the consequences that mismanagement can have on a community.
David Thewlis and Jason Watkins sustain the miniseries’ pulse
One of the main attractions of Shady Business lies in the pair of David Thewlis and Jason Watkins. The fiction uses the relationship between their characters to add a more human dimension to a plot that could have limited itself to exposing corporate irregularities.
The duo brings tension, irony, and a dynamic less solemn than one might expect given the gravity of the matter. That contrast is key: the story tackles pollution, cover-ups, and corporate responsibility, but finds room for its leads to relate naturally and drive the investigation forward through a mix of stubbornness, experience, and a sense of humour.
Critics have also highlighted precisely that balance. The series can adopt a harsh tone when showing the consequences of the conflict, but it does not shy away from moments of dry humour that prevent the drama from becoming a monocultural sermon.
Why it fits among Britain’s investigative thrillers
The premise connects with a well-recognised tradition of British television: stories where ordinary citizens confront corporate or institutional structures that are too large for them. The difference here is that the starting point isn’t a scandal already explained, but a specific anomaly that forces the protagonists to piece together what happened.
That approach allows the viewer to uncover the problem alongside the characters. First come the dead fish and the inadequate explanations; later come the decisions that have worsened the situation and the doubts about who knew the scope of the problem. The investigation progresses through the accumulation of clues, rather than through grand, isolated revelations.
There is also a clear industrial reading. The series highlights the distance between a company that provides an essential service and the neighbours who depend on it, a relationship in which a lack of transparency can turn a local incident into a crisis of trust. You do not need to know the exact details of the real case to understand the concern raised by the fiction.
A recommendation for those seeking a brief series with something to say
Shady Business may especially appeal to anyone who enjoys thrillers based on real events, investigative dramas, and stories of communities facing companies with more resources and power. Its strongest asset is not only the mystery surrounding the death of the fish, but the way it transforms that fact into an uncomfortable question: how long can a community take before realising that the official explanation does not fit?
The proposition blends a recognisable conflict, two performers with real presence, and an environmental theme treated from the perspective of human consequences. It is a recommended choice on Movistar Plus+ for those who prefer a British miniseries with progressive tension, restrained humour, and a critique that remains within the realm of entertainment.
The 100% Rotten Tomatoes rating serves as a lure, but the reason to approach it lies elsewhere: it confronts a silent threat with characters who do not appear as traditional heroes. And precisely because of that, the story feels more relatable when the indignation ceases to be a momentary reaction and becomes the only way to keep asking questions.
