Staff Writer at Screen Rant by day, horror enthusiast by night.
Amazon Prime Video has no shortage of great sci-fi shows. From the radioactive wastelands of Fallout to the satirical superhero carnage of The Boys and even short-lived curiosities like The Peripheral, the platform has invested heavily in big ideas and bigger budgets.
Yet for all their spectacle, no sci-fi show on Prime matches The Expanse. Calling The Expanse merely good is an understatement. The six-season space opera stands as one of the most accomplished sci-fi series of the last few decades, blending grounded physics, layered politics, and rich character drama into something that feels genuinely epic. Critics praised it, fans adored it, and its cinematic scope constantly pushed the limits of television storytelling. Since the series concluded in 2022, Prime Video has launched multiple high-profile sci-fi series with blockbuster production values and ambitious stories and concepts. Still, none match the precision, scale, or narrative confidence of The Expanse. It still remains the benchmark for Prime’s sci-fi shows, and that doesn’t look set to change anytime soon. The Expanse Is The Best Sci-Fi Show On Prime Video Hard Science Fiction Merges With Prestige Drama For An Unmatched Experience There are plenty of reasons The Expanse remains the best sci-fi show on Prime years after it concluded. Firstly, there’s its commitment to treating science fiction seriously. Space travel obeys physics. Gravity matters. Bullets tear through hulls with terrifying realism. Every dogfight feels dangerous, not flashy. That grounded approach gives the show a weight most sci-fi series simply can’t replicate. However, realism isn’t the only thing that sets The Expanse apart. The show functions equally well as a political thriller and character drama. James Holden begins as an idealist caught between factions, while Naomi Nagata , Amos Burton , and Alex Kamal feel like working-class survivors rather than archetypal heroes. Meanwhile, Chrisjen Avasarala steals scenes with razor-sharp diplomacy and ruthless pragmatism, turning interplanetary politics into gripping television. On the other side of the Belt, Josephus Miller gives the noir-tinged early seasons emotional depth. These characters aren’t props for spectacle. They drive the story of The Expanse just as much as its interstellar setting and space opera spectacle. Few Prime Video sci-fi series balance conceptual scale and character-driven intimacy this effectively. Massive conflicts unfold alongside personal tragedies. Even as later seasons escalate into system-wide wars, The Expanse never loses sight of the people caught in the crossfire. Then there’s presentation. Visually, The Expanse rivals blockbuster sci-fi movies. Zero-G shootouts, claustrophobic neon-flooded space stations, and the eerie visual aesthetic of the protomolecule feel expensive and deliberate. Nothing looks disposable. Every design choice reinforces the prestige feel that has led many to describe The Expanse as being akin to Game of Thrones in space. Other Prime Video sci-fi shows may deliver fun or shock value, but The Expanse delivers immersion. It doesn’t just entertain. It convinces viewers that this future could exist. That authenticity is why it’s still considered by many to be the best sci-fi series on Amazon Prime, despite concluding years ago. Why The Expanse Never Became As Big As It Should've Been Weak Early Marketing And A Slow-Burn Start Limited Its Mainstream Breakout For a show so consistently excellent, The Expanse never reached the cultural dominance it deserved. Timing and platform played a major role. The first three seasons aired on Syfy, a network that struggled to market prestige dramas beyond its core audience. Despite critical acclaim, The Expanse often felt invisible compared to splashier franchises. Casual viewers simply didn’t know it existed. Without aggressive promotion or viral buzz, it built a loyal fanbase slowly instead of exploding into the mainstream. The cancellation by Syfy after season 3 proved the problem. Only after fans campaigned loudly did Amazon rescue The Expanse. Ironically, that move elevated production quality and visibility, but the damage had been done. The audience should have been much bigger from day one. Its structure also worked against it. The early seasons of The Expanse demand patience. Politics, factions, and terminology are introduced gradually, and the central mystery unfolds methodically. Its complex storytelling is closer to a dense drama than an easily bingeable sci-fi streaming phenomenon. While rewarding in the long run, that deliberate pacing can be intimidating for newcomers. It’s a rare case where quality wasn’t the issue. Exposure was. Had The Expanse launched on Prime Video from the start with stronger marketing, it might have become the defining sci-fi show of the decade rather than an underappreciated masterpiece. Prime Video Should Bring The Expanse Back Unfinished Stories And A Growing Fanbase Make A Comeback Feel Necessary While The Expanse has wrapped up its story, there are plenty of reasons Prime should bring the epic space opera back. For starters, there’s still more story to tell. Even with six seasons, The Expanse never fully exhausted its source material.

Corey’s novels, and several books hadn’t been adapted by the time the conclusion to The Expanse season 6 had arrived. Entire arcs involving new threats, political upheavals, and generational consequences are still waiting to be explored. That untapped story potential is rare. Most sci-fi show revivals rely on nostalgia alone, and have to figure out a justifiable reason to continue the story. The Expanse, on the other hand, has fresh narrative fuel ready to go. The groundwork is already there, and the universe is expansive enough to support multiple directions, from direct continuations to spin-offs. The also the fact that the fanbase of The Expanse has grown since the finale. Continued discussion online and praise from fans and critics alike long after the show's conclusion has introduced new viewers every year. What once felt niche now feels essential viewing for sci-fi fans. A return today would likely debut to far greater hype than the original run ever achieved. From a business perspective, bringing the show back also makes a lot of sense. The Expanse already proved it can deliver prestige storytelling and blockbuster visuals that hold interest from fans long term. As far as Amazon Prime is concerned, reviving it would be far less risky than launching another expensive unknown sci-fi show. For fans, there’s a simpler reason that a return to The Expanse would be welcomed - the universe of the show feels too big to leave behind. If Star Trek can last for decades with multiple series and regular reinvention, The Expanse definitely can. Bringing it back wouldn’t just satisfy fans, it would elevate Prime Video’s greatest sci-fi achievement to the mainstream like it’s always deserved. 280 9.4/10 10/10 The Expanse 10 stars 9 stars 8 stars 7 stars 6 stars 5 stars 4 stars 3 stars 2 stars 1 star Like Follow Followed TV-14 Drama Mystery Science Fiction Thriller Release Date 2015 - 2022-00-00 Network SyFy, Prime Video Showrunner Naren Shankar, Mark Fergus, Hawk Ostby Directors Breck Eisner, Jeff Woolnough, David Grossman, Kenneth Fink, Rob Lieberman, Terry McDonough, Thor Freudenthal, Bill Johnson, David Petrarca, Jennifer Phang, Mikael Salomon, Sarah Harding, Marisol Adler, Anya Adams, Nick Gomez, Simon Cellan Jones Writers Georgia Lee, Robin Veith, Hallie Lambert, Matthew Rasmussen, Ty Franck, Naren Shankar, Mark Fergus, Hawk Ostby, Daniel Abraham, Dan Nowak Cast See All
