Netflix canceled Jupiter’s Legacy in the same year it premiered, and the show does not make much of a case for a second season. Steven S. DeKnight developed the series from the 2013–2025 comic book by Mark Millar and Frank Quitely, and DeKnight was replaced as showrunner by Sang Kyu Kim midway through production. The eight episodes arrived on May 7, 2021, and they want to be a generational epic about power and inheritance. They settle for a slow setup that spends most of its run explaining a mythology it never makes us feel.

Sheldon Sampson Builds a Team in 1929
The premise is the strongest thing here. After his father’s suicide in 1929, triggered by Black Thursday, former businessman Sheldon Sampson travels to an uncharted island in the Atlantic Ocean. He goes with his brother Walter and four others. On that island they receive superpowers. Sheldon then creates a superhero team called the Union of Justice, and his guiding ideals — never kill anyone, never interfere in political matters — remain unchanged across the near-century of his adventures as the Utopian.
Josh Duhamel plays Sheldon, and the show casts him as the revered elder guard of the present day. Ben Daniels is Walter Sampson, also called Brainwave. Leslie Bibb is Grace Sampson, or Lady Liberty. The cast is filled out by Andrew Horton as Brandon Sampson, Elena Kampouris as Chloe Sampson, Mike Wade as Fitz Small, and Matt Lanter as George Hutchene, also known as Skyfox.
That is a real ensemble, and the premise has a real idea in it. A man who got his powers during the Depression turned those powers into a rigid moral code. His children inherited the powers but not the world that made the code make sense.
As a starting point, that is strong.
Where the Children Fall Short
The next generation is where the series puts its actual drama. Sheldon’s children and their peers struggle to live up to his rigid ideals and high expectations. The synopsis is blunt about it: the children struggle to live up to the legendary feats of their parents.
Brandon, played by Horton, is the son trying to be his father. Chloe, played by Kampouris, is the daughter who has stopped trying. The show keeps circling this conflict without landing on a scene that makes the cost concrete. We are told the expectations are crushing. We are rarely shown the crushing.
Then the plot turns. When Sheldon’s son Brandon seemingly kills one of their greatest foes to save Sheldon’s life, it ignites a public debate over whether those ideals are still relevant. That is the engine of the back half, and it is a good engine. A superhero who breaks the one rule his father built the whole team around should be a fracture point for everything.
A Debate Nobody Actually Has
Here is where Jupiter’s Legacy loses its grip. The public debate over the ideals is announced more than it is dramatized. The show tells us the world is arguing about whether the Union of Justice still matters. It does not build the argument. We do not get the shouting, the factions, the people who think Sheldon is a relic and the people who think he is the only thing holding the line.
A superhero story about inherited morality lives or dies on whether the morality feels contested. In my reading, this one plays like a synopsis read aloud. The premise has the pieces — a founding myth, a dead father, a son who crosses a line, a public that wants an answer. The season never makes them collide.
The mystery and fantasy labels in the show’s genre tags promise something stranger than what the episodes deliver. The 1930s origin, the island, the powers — the source treats all of it as backstory, and the series follows that lead. What the present-day material does with it is thinner than the setup deserves.
DeKnight Out, Kim In
DeKnight developed the series and initially served as showrunner. He was replaced by Sang Kyu Kim midway through production. The source records the handoff and nothing more about it, so the swap is worth noting as a fact about the season, not as an explanation for how it turned out.
Casting news rolled out over more than a year before release. Duhamel, Daniels, Bibb, Kampouris, Horton, Wade and Lanter were announced in February 2019. Tenika Davis was reported in a recurring role that April. Chase Tang was reported as a supervillain that August. Anna Akana was cast in a recurring role in September 2020.
That is a long runway for a first season. What the eight episodes do with it is the part that matters, and the answer is not much.
Supercrooks, and the Spin-Off That Never Came
The cancellation came with a strange afterlife. A spin-off continuation, a live-action adaptation of the 2012 comic book Supercrooks, was ordered to series to release 2021–2022. It was never produced as of December 2025.
What did arrive was Super Crooks, an anime adaptation of Supercrooks set in the same fictional universe as Jupiter’s Legacy, preceding the additional live-action series. It was released to Netflix in November 2021.
So the universe survived the show that launched it. That is an odd legacy for a series that could not get its own second season. Netflix ordered the continuation and never made it, which is its own verdict on where the franchise stood.
Duhamel and Daniels Hold the Center
The cast is not the problem. Duhamel has the right weight for a man who has been right for a hundred years and cannot imagine being wrong. Daniels plays Walter with a stillness that suggests something is being held back, which is the correct read for a character named Brainwave. Bibb, in my view, gets less to do than the part deserves, and that reads as a writing problem rather than a performance one.
The central question is also the right one. What happens when the people who wrote the rules are still alive to enforce them, and the people who have to live under those rules did not choose them? That is a question about inheritance, about politics, about families. It is a question a superhero show can ask better than almost any other kind of show.
Jupiter’s Legacy asks it and then walks away from it. In my view, the show is more interested in the fact of the debate than in the debate itself.
The Verdict on Jupiter’s Legacy
Mixed reviews greeted the series on release, and the published critical score sits at 4.5/10, with a Metacritic score of 45/100. That is the right neighborhood. This is not a disaster. It is a waste.
The waste is specific. A great premise, a solid cast, a genuine moral question, and a season that never finds the scene where any of it costs anything. The show’s best idea — that Sheldon’s code is both his gift and his cage — is stated in the synopsis and, in my view, never dramatized in the episodes. The son’s killing should be the moment the whole thing cracks open. It plays like a plot point.
There is a version of Jupiter’s Legacy that is a great show. You can see its outline in the premise. The version Netflix made is a pilot for that show, stretched to eight episodes, and then canceled before it could become anything.
Key facts

In my view, the cancellation is not the most interesting fact about Jupiter’s Legacy. Shows get canceled. What matters is that this one had a real question at its center and could not bring itself to answer it or even to argue about it out loud. The spin-off universe moved on without it, and that feels correct. The show was a setup for something that never came. 4.5 of 10.
