10 Best Sci-Fi Shows on Prime Video: Prime Video may be widely known for fantasy epics, but its science fiction catalog is quietly one of the strongest in streaming. From dystopian alternate histories to space operas, animated mind-benders, and post-apocalyptic adventures, Amazon’s platform offers an impressive variety of sci-fi storytelling — both originals and timeless classics.

Here’s a deep dive into 10 of the best sci-fi shows you can stream on Prime Video right now with a base subscription.

1. The Man in the High Castle (2015–2019)

Based on Philip K. Dick’s novel, The Man in the High Castle imagines an alternate 1960s where the Axis powers won World War II. America is split between Nazi-controlled eastern states and Japanese rule in the West.

The show explores resistance movements, authoritarian control, and chilling ideological oppression. Its sci-fi twist revolves around mysterious films showing alternate realities — worlds where the Allies won the war.

Dark, morally heavy, and ambitious in scope, this remains one of Prime Video’s earliest and most impactful original dramas.

Why watch?

• Intense alternate history concept
• Multi-layered political storytelling
• Sobering and thought-provoking themes

2. Tales from the Loop (2020)

Inspired by the artwork of Simon Stålenhag, Tales from the Loop is quiet, emotional, and visually stunning.

Set in a small town built above a mysterious research facility called “The Loop,” each episode explores strange phenomena — body swaps, time freezes, unusual machines — through deeply personal stories.

Unlike high-adrenaline sci-fi, this show focuses on mood and human connection. It feels closer to The Twilight Zone in structure, but with a softer, melancholic tone.

Why watch?

• Beautiful cinematography
• Emotional storytelling
• Hypnotic soundtrack by Philip Glass

3. Fallout (2024– )

Video game adaptations have finally found their groove — and Fallout proves it.

Set in a retro-futuristic post-nuclear wasteland, the show blends dark humor, western vibes, and brutal survival drama. It captures the tone of the beloved game franchise while standing strong as its own series.

With standout performances and sharp writing, it’s both fan-friendly and accessible for newcomers.

Why watch?

• Unique retro-Americana aesthetic
• Balanced action and comedy
• Expanding universe with future seasons

4. Undone (2019–2022)

Visually unlike anything else on Prime, Undone blends live action with rotoscope animation.

The story follows Alma, who begins experiencing unusual time distortions after a car accident. As she reconnects with her deceased father, the show unfolds into a layered exploration of trauma, family, and reality itself.

Why watch?

• Innovative animation style
• Emotional and philosophical storytelling
• Smart, character-driven sci-fi

5. Farscape (1999–2003)

Produced with involvement from The Jim Henson Company, Farscape delivers one of the most imaginative space adventures ever made.

Following astronaut John Crichton stranded in a distant galaxy, the show combines camp, practical creature effects, and serialized storytelling.

Why watch?

• Memorable alien designs
• Cult-favorite status
• Influenced modern space operas

6. Outer Range (2022–2024)

What happens when a modern western collides with cosmic mystery? You get Outer Range.

A rancher discovers a strange void on his land, triggering events that blur the line between science fiction and existential drama.

Why watch?

• Western-meets-Twilight-Zone vibe
• Strong performances
• Atmospheric and mysterious

7. The Boys (2019– )

Superheroes — but corrupted by corporate greed and unchecked power. That’s the premise of The Boys.

Violent, sharp, and satirical, the show deconstructs the modern superhero mythos with unapologetic intensity.

Why watch?

• Bold social commentary
• High-stakes action
• One of Prime’s biggest hits

(Not for the faint of heart.)

8. Stargate SG-1 (1997–2007)

A true genre classic, Stargate SG-1 expanded the Stargate universe into a 10-season epic.

Blending military procedural storytelling with ancient alien mythology, it offers deep lore and endless adventure.

Why watch?

• Massive binge potential
• Expansive sci-fi mythology
• Beloved long-running franchise

9. Night Sky (2022)

Under-the-radar gem Night Sky stars Sissy Spacek and J.K. Simmons as a couple who discover a portal to another world hidden in their backyard.

It’s less about spectacle and more about aging, love, and curiosity.

Why watch?

• Intimate sci-fi storytelling
• Powerful lead performances
• Emotional and mysterious

10. The Expanse (2015–2022)

Many consider The Expanse the best modern sci-fi television series.

Set in a colonized solar system divided by political tension, the show follows the crew of the Rocinante as they uncover galaxy-altering conspiracies.

Amazon rescued it after cancellation — and completed the story in grand fashion.

Why watch?

• Realistic space science
• Political intrigue
• Epic character arcs
