Despite being one of the most critically acclaimed sci-fi shows of all time,The Expansewas canceled twice. Based on the book series by James S.A. Corey (a pen name for author duo Daniel Abraham and Ty Franck),The Expansetakes place in the far future and follows a large cast of compelling characters. Humanity has colonized the solar system, but the peace between Earth, Mars, and the asteroid belt is fragile at best. Although the series begins as a gritty sci-fi murder mystery, it eventually becomes a sprawling space opera with enoughpolitical intrigue to rivalGame of Thrones.

In its first season,The Expansecenters on Detective Joe Miller (Thomas Jane) and his investigation into the disappearance of Juliette Mao (Florence Faivre). This search eventually leads Miller to connect with James Holden (Steven Strait)and his crew aboard the Rocinante, and they soon get caught up in a massive conspiracy involvingThe Expanse’s dangerous bio-weapon known as the protomolecule.The scope ofThe Expanseonly gets larger as the show progresses,with each season adding new characters and new complications.

Hard sci-fi is a genre that is often overlooked at major award shows like the Emmys, butThe Expansewas regularly praised by critics across the board.The series has a 95% critic rating on Rotten Tomatoesand an 85% audience rating, making it one of the highest-rated sci-fi series of all time.

The Expanse Was Canceled Twice Despite Its Success With Audiences And Critics

The Expanse Was Canceled By Syfy & Later Canceled Again by Amazon

Mediocre viewing numbers and a complicated rights agreement led SyFy to cancelThe Expanseafter its first three seasons. By this point,The Expansehad developed a passionate fanbase who campaigned for the showto be picked up by Amazon Prime Video, who already had the streaming rights. Thankfully, Amazon CEO Jeff Bezos was reportedly a fan ofThe Expanseand helped facilitate its move to the platform. While the show continued for another three seasons on Amazon Prime Video, they eventually canceled it, too.

Each season ofThe Expanseroughly covers the events of one book in the series, meaning the show’s six seasons cover only the first six books. However, there is a nearly 30-yeartime jump betweenThe Expansebooks six and seven, which may have contributed to the show’s cancellation. The main reason for the cancellation, however, likely came down to the show’s budget. With its epic space battles, sprawling settings, and large cast of characters,The Expansesurely wasn’t cheap to produce,and in the end, the viewing numbers simply didn’t justify the cost for future seasons.

The Expanse Is One Of Many Examples Of Sci-Fi Shows That Struggled To Keep Going

The Expanse Is Far From The Only Sci-Fi Show Canceled Too Soon

The Expanseisn’t the first (and likely won’t be the last) sci-fi show that struggled to find and keep its audience. From classics likeFireflyto more recent gems likeHBO Max’sRaised by Wolves, high-concept science fiction shows regularly get canceled prematurely.Even being a part of a beloved franchise cannot save some shows,as was the case withStar Trek: EnterpriseandStargate Universe.These canceled shows often left viewers with unanswered questions, as the writers did not always get enough notice to wrap up the storylines properly.

Boom! Studios published a comic book series calledThe Expanse: Dragon Toothby Andy Diggle, which picks up after the show’s sixth season and fills in the thirty-year gap before book seven,Persepolis Rising.

The Expanse’s final season only consisted of six episodes, as opposed to every other season’s 10 or 13, but it still managed to wrap up many of the series' main storylines. Still, the series finale left several lingering questions, and the book series has three more novels' worth of story for Holden and his friends. Like many canceled sci-fi shows,The Expanseseemingly had everything going for it.It was based on existing IP, had a dedicated fan base, and was praised by critics, but none of these things were enough to save it from cancellation.
