Quick answer: Black Sails is the stronger pick for viewers who want an expansive pirate society, political intrigue, and character arcs that develop across multiple seasons. The 2026 Treasure Island is a separate kind of adaptation: it returns directly to Robert Louis Stevenson’s story, expands Bess Hawkins’s role, and adds a heightened memory ability for Jim. If “authentic” means historical accuracy, neither series is a documentary. If it means a convincing dramatic world, Black Sails has more time to build one; if it means seeing a classic adventure reinterpreted, the new Treasure Island offers the fresher experiment.
The comparison is timely: Paramount+ lists the six-part adaptation for the UK and Ireland from October 12, 2026, while the series premiered in the US on MGM+ on October 11. Tom Sweet plays Jim Hawkins, Hayley Atwell plays Bess, and David Oyelowo plays Long John Silver. Paramount+ calls it a reimagining of the classic, not a strict page-by-page retelling.

1. Authenticity is more than weathered ships and costumes
A pirate show can feel authentic in several different ways: its ships and clothes look tactile, its characters behave as if food and money matter, or it respects the source material. These standards do not always agree. A beautifully dressed pirate can still be fictional, and a faithful adaptation can still lack dramatic momentum.
Black Sails uses Stevenson’s world as a foundation but does not simply dramatize every event in the book. Netflix’s overview says the show takes place about two decades before Treasure Island and combines characters from the novel with historical figures. That gives the writers room to build conflicts beyond the treasure hunt. Netflix Tudum explains the connection here.
The new Treasure Island has a different challenge: make an often-adapted adventure feel fresh without losing Jim’s coming-of-age journey. Its photographic-memory twist and expanded Bess role are bold departures. The question is whether those choices deepen the story or crowd out the young hero—not whether change is automatically a mistake.
2. Why Black Sails feels like the fuller pirate world
The biggest advantage of Black Sails is not simply the size of its ships; it is the number of competing interests shaping each decision. Characters bargain, threaten, make alliances, and betray them. Nassau feels like a place where survival and commerce intersect, rather than a backdrop that exists only until the next sword fight. Supporting characters also have room to change, sometimes in ways that complicate viewers’ loyalties.
That does not make the series a history lesson. A historical-accuracy analysis by Colonies, Ships, and Pirates notes that screen productions often compromise on costume details, ship types, and material culture to meet budgets and audience expectations. The same caution applies to any pirate show: strong production design can create a convincing atmosphere while still taking liberties. Read the historical-accuracy analysis.
The show’s reputation should not erase its uneven early reception. Rotten Tomatoes’ Season 1 page records a critics’ consensus that praised the visual appeal but criticized characterization and exposition. That is a useful reminder that no series works equally well in every episode. Check the Season 1 review page.
3. What the new Treasure Island does differently
The 2026 adaptation has a tight, familiar engine: a map, a dangerous voyage, competing claims to treasure, and a boy learning whom to trust. Its most distinctive choice may be giving Bess Hawkins a much larger role. That can make the family stakes more immediate and give the story an emotional center missing from versions that leave Jim almost entirely on his own.
But expanding Bess creates a balancing act. If her choices drive every major turn, Jim can lose the agency that makes the novel a coming-of-age adventure. The same applies to Jim’s unusual memory: it can make the map plot distinctive, but it risks turning the hero into a device unless he still makes consequential choices.
The Guardian’s October 12 review criticized the added plot devices and argued that Jim is pushed into the background, while praising Oyelowo’s commanding presence. That is one critic’s view, not a universal audience verdict, but it identifies the central trade-off: does reinvention sharpen the adventure, or crowd out its young hero? Read The Guardian review.
4. Ships, costumes, and atmosphere
Black Sails had four seasons to establish recurring locations and a visual language. Weathered decks and crowded ship spaces help sell the labor and danger of maritime life. Yet historical analysis has identified familiar screen shortcuts: larger vessels than many pirates used, costume choices that do not always fit the precise period, and cinematic staging designed for spectacle.
For Treasure Island, the test is not which show has the darkest lighting or most battered wood. It is whether the production details support the story. A ship feels convincing when its layout shapes who can overhear a conversation, where a crew can hide, and how authority is enforced—not merely when it looks good in a wide shot.
5. Long John Silver: a strong performance is not the whole story
Oyelowo’s Silver is a clear reason to give the new adaptation a chance, even for viewers who prefer Black Sails. The Guardian singled out his performance despite broader objections to the series. Silver works best when charm and self-interest coexist: he should be more than a stock villain with a parrot.
Still, one excellent performance cannot solve every structural problem. Black Sails has more time to show how loyalties shift under pressure. The six-part Treasure Island may develop its own version of that complexity, but early reviews should not be mistaken for a final season verdict.
6. Watch the official Treasure Island trailer
Compare the trailer’s emphasis on family, memory, Silver, and the voyage with the broader political world of Black Sails.
Verdict: which pirate series should you watch?
Choose Black Sails if you want a long-form ensemble drama, political maneuvering, morally complicated characters, and a pirate setting that grows across several seasons. It has more room for the world beyond the treasure map, though it also takes historical and literary liberties.
Try Treasure Island (2026) if you want a classic reworked around Bess Hawkins, a different Jim, and Oyelowo’s Long John Silver. Early criticism raises fair questions about pacing and focus, but the series is not interchangeable with Black Sails: it is attempting a more direct retelling with different dramatic priorities.
Our take: Black Sails is the stronger choice for viewers who define pirate authenticity through a detailed social world and long-term character arcs. Treasure Island is the more relevant watch for readers curious about how a modern adaptation changes a familiar literary adventure. The fair comparison is not “old show good, new show bad”; it is whether each version’s inventions deepen the story it wants to tell.
Frequently asked questions
Is Treasure Island (2026) connected to Black Sails?
No direct production connection has been announced. Black Sails is a prequel-inspired drama using characters and ideas from Stevenson’s novel; the 2026 Treasure Island is a separate adaptation.
Which series is more historically accurate?
Neither should be treated as a documentary. Black Sails mixes historical pirates with invented events, and historians have identified material-culture compromises in its costumes, props, and ships. A gritty look is not the same as full historical accuracy.
Is the 2026 Treasure Island faithful to the book?
It retains the treasure-map adventure and central figures but makes major changes, including a larger role for Bess and a heightened memory ability for Jim. Readers who prioritize strict fidelity may find those choices divisive.
Is Black Sails more violent than Treasure Island (2026)?
Black Sails is known for a more adult mix of violence, sexuality, and political conflict. The 2026 series also includes danger and violence; check each platform’s content guidance if choosing for younger viewers.
Where can I watch Treasure Island (2026)?
Paramount+ UK and Ireland lists the series, while MGM+ carries it in the United States. Availability can vary by country and subscription.
Should I watch Black Sails before Treasure Island?
No. They can be watched independently. Start with Black Sails for a broad pirate-world drama, or Treasure Island for a fresh adaptation of Stevenson’s story.
