When it comes to sci-fi television, streaming platforms like Netflix, Disney+, and Amazon Prime Video are all in fierce competition to deliver some of the most captivating and creative series. But amid all the popular shows, one standout on Prime Video has earned the title of best sci-fi series of the 21st century. And the surprising part? It’s not getting the widespread attention it truly deserves. So, what is this hidden gem? It’s none other than The Expanse.
The Expanse: A Hidden Gem in Science Fiction
As a sci-fi fan, I know firsthand how overwhelming it can be to choose which series to dive into. With the genre’s long history on TV—from Star Trek to Battlestar Galactica to Doctor Who—there’s no shortage of options. But in the midst of this sea of shows, The Expanse stands out as a deeply complex and compelling tale that should not be overlooked.
Released in 2015 and concluding in 2022 after six seasons, The Expanse was initially aired on Syfy, before Amazon Prime Video took over production starting from season four. Based on the book series by James S.A. Corey, this show is set in the 24th century, where humanity has colonized the solar system. Earth, now governed by the United Nations, is dependent on resources imported from colonies across space. The planet’s natural resources have been depleted, and tensions rise among the factions vying for control.
A Complex Web of Characters and Conflicting Factions
At the heart of The Expanse is a series of intertwined character arcs, each representing different factions—Earth, Mars, and the Belters (those living in the asteroid belt). Mars is an independent, technologically advanced planet, while the Belters endure harsh living conditions, caught between the economic and political dominance of Earth and Mars. The intricate relationships between these factions create an ever-deepening sense of conflict that drives the series forward.
One of the reasons The Expanse has captivated viewers is its ability to navigate the shifting narratives of individual characters, while subtly connecting them across the larger geopolitical landscape. Watching the characters’ lives unfold across multiple layers of tension, betrayal, and survival, you can’t help but become invested in their fates. It’s a series that constantly keeps you on the edge of your seat, never losing its thrill or momentum.
The Expanse: Ranked #1 in Sci-Fi TV of the Century
The acclaim for The Expanse is not just from fans—it’s been critically lauded across the board. With an average score of 95% on Rotten Tomatoes, the show clearly struck a chord with both critics and audiences. The series also boasts an impressive 88% audience rating, reflecting its broad appeal.
Beyond these scores, The Expanse has garnered Hugo Awards for Best Dramatic Presentation and multiple other accolades for its storytelling and production quality. But perhaps the most significant recognition came from Movie Pilot, which ranked it as the best sci-fi series of the 21st century. This was no small feat, especially considering the intense competition in the genre.
Why The Expanse Deserves Your Attention
The beauty of The Expanse lies in its ability to juggle multiple genres while maintaining its sci-fi integrity. The show isn’t just about spaceships and planetary politics—it’s also a police thriller, a survival horror, and a deeply psychological journey into human nature. Each episode offers something for everyone, from intense mystery-solving to exploration of the unknown.
According to a Movie Pilot journalist, The Expanse makes viewers “feel the constant uncertainty of space, hanging over us like a sword of Damocles with every fleeting moment of respite.” This tension is something the series does expertly, keeping you on edge throughout. What’s more, it never gets monotonous—it consistently offers fresh perspectives and thrilling developments that keep you hooked from start to finish.
The Expanse: Not Just Another Sci-Fi Show
In a world flooded with high-budget sci-fi series, The Expanse stands apart because of its sharp narrative focus and emotional depth. It’s not just about futuristic gadgets or space battles; it’s a profound exploration of the human condition, our frailties, and how we manage conflict in an increasingly divided world. The show has all the hallmarks of a great series—complex characters, riveting plotlines, and world-building that feels real, even if it’s set far in the future.
If you haven’t yet experienced The Expanse, now’s the perfect time to dive in. It’s a show that’s often overshadowed by others in the sci-fi genre but deserves to be in the spotlight. So, put down the remote for a minute and give this underrated masterpiece a chance—you’ll be glad you did. Prime Video has delivered a sci-fi experience that’s rich, layered, and truly unforgettable.
