With autumn in full swing in some parts of the world, the season brings a fresh wave of supernatural and sci-fi delights to television and streaming services. While some releases that started in August kind of counts, I must mention Alien: Earth along with Peacemaker. But for the official start of the season, here are five other sci-fi and fantasy series 2025 that I’m most looking forward to checking out this fall and winter.
And at long last, the much-anticipated finale of Secret Things is arriving—a conclusion that’s been years in the making. But I have to begin with:
Talamasca: The Secret Order (AMC)
Premieres: October 26, 2025The Talamasca has long been whispered about in Anne Rice’s gothic novels, but this series finally puts them under the spotlight. As supernatural auditors, they keep tabs on vampires, witches, and all things that go bump in the night. On screen, that mix feels like The X-Files with rosaries and velvet capes. Launching just before Halloween, AMC is clearly betting that occult espionage and candlelit conspiracies will hook fans old and new.
Pluribus (Apple TV+)
Premieres: November 7, 2025 (two-episode launch)
From the team that gave us Severance comes a new nine-part series that promises to probe the ethics of power and technology. Pluribus looks polished, eerie, and loaded with allegory. If Black Mirror had a sibling that was less anthology and more serialized thriller, this would be it. With Apple’s knack for moody prestige sci-fi, this one could ignite serious water-cooler debates.
The Mighty Nein (Amazon Prime Video)
Premieres: November 19, 2025
Critical Role isn’t slowing down. If The Legend of Vox Machina captured the spirit of high-energy campaigns, The Mighty Nein dives into murkier waters. This crew is scrappy, emotional, and gloriously messy—a perfect match for fans who like their fantasy tangled with moral ambiguity. Expect dazzling animation, sharp humour, and references that will reward long-time Critters while still staying friendly for newcomers to Exandria.
Returning Favourites
Stranger Things — Final Season (Netflix)
Begins: November 26, 2025 (Volume 1)
The Hawkins saga has always been more than just monsters—it’s a love letter to the 80s, stitched together with friendship and nostalgia. The final season arrives in three parts, carrying fans through Thanksgiving, Christmas, and into New Year’s Eve. Few series have defined a decade of streaming like this one, and its conclusion is poised to be an event. Whether it sticks the landing alongside the greats remains to be seen, but one thing’s certain: Stranger Things is ending on its own terms, fireworks and all.
Marvel Zombies (Disney+)
Premieres: September 24, 2025
The Marvel multiverse takes a grotesque detour as Earth’s mightiest heroes become flesh-eating nightmares. With returning MCU voice talent, this isn’t just a side story—it’s Marvel embracing horror. The art style is bloodier, the tone darker, and for fans of the original comic run, this is long overdue.
Honourable Mentions: Network TV
Streaming dominates the landscape for bold sci-fi and fantasy, but a few network shows still merit a glance for casual genre fans. These are ongoing series:
- Ghosts (CBS) – A supernatural comedy blending humor with light ghostly adventures, perfect for fans looking for something fun without diving too deep into horror.
- La Brea (NBC) – A sci-fi mystery exploring a massive sinkhole in Los Angeles that leads to a prehistoric world. It’s tense, adventurous, and network-friendly.
