If you’re looking for a good fantasy TV show to binge this week (September 16, 2025), ScreenRant has five great options for Prime Video subscribers. Whether you’re on the hunt for a completed series that you can binge from beginning to end, or a TV show that will serve as a longer-term commitment, this streaming platform will have you covered. One of these hit fantasy series can even carry you into its upcoming spinoff.
When it comes to a great fantasy series, streaming services have almost too many options. This genre is currently booming, but that makes choosing a series to watch an even greater risk. There’s nothing worse than falling in love with a fantasy TV show, only to suddenly find it canceled or significantly delayed. Thankfully, Prime Video has some offerings that are unlikely to let you down.
If your tastes extend beyond fantasy, we have more streaming recommendations to offer. Be sure to check out ScreenRant‘s selections for Hulu and Disney+, HBO Max, and Netflix.
The Addams Family
The Addams Family is easily one of the more unique and iconic fantasy franchises around, and Prime Video has the original sitcom series available to stream in its entirety. Based on the spooky but lovable comics from creator Charles Addams, The Addams Family centers on an aristocratic family that completely contradicts expectations. They are macabre, creepy, and entirely delightful.
The Addams Family sitcom is just one of the many adaptations within this franchise, but it’s a must-watch for anyone who claims to love all things Addams. The series is made up of two seasons and 64, 26-minute episodes, making it an effortless binge. Originally airing between 1964 and 1966, The Addams Family is a wholly nostalgic sitcom, and the perfect way to usher in the fall season.
Now is an especially good time to binge The Addams Family, given the recent popularity of Netflix’s Wednesday series. The spinoff features many of the same characters and plays off these original stories, though this may go unnoticed by those who haven’t seen the 20th-century sitcom. These series aren’t directly related, but they’re still franchise staples.
Grimm
Grimm is a dark fantasy procedural drama series following Portland homicide detective Nick Burkhardt, who learns he is descended from a storied line of “Grimms.” These are hunters tasked with keeping the balance between humans and mythological creatures. Grimm brings all the thrills of procedurals like NCIS, combined with fantastical tales of folklore.
Prime Video has all six seasons (123 episodes) of Grimm available to stream, so if you are looking for a good, long-running fantasy binge, this is the series for you. Each episode is about 43 minutes long, so Grimm should take a good long while for even the most dedicated TV bingers to get through. Still, that monster-of-the-week format carries Grimm easily along, all the while, character development never disappoints.
Grimm ran from 2011 to 2017, so there is a decent amount of nostalgia tied up in this series as well. Since Grimm Fairytales are among the foundations of fantasy, it’s a shoo-in within the genre. Though you may not find as massive a fanbase as Game of Thrones to engage with after binging Grimm, this series had a fair cultural impact all the same, influencing further series that mix crime, myth, and horror.
The Lord Of The Rings: The Rings Of Power
The Lord of the Rings: The Rings of Power is Prime Video’s exploration of Middle-earth’s Second Age, serving as a prequel to Tolkien’s central Lord of the Rings series. Set thousands of years before Frodo’s journey, The Rings of Power explores Sauron’s rise to power after the Dark Lord Morgoth’s downfall, as well as the creation of his infamous Rings of Power—including the One Ring.
Rings of Power isn’t yet complete, but now is the perfect time to binge the existing two seasons. Season 3 isn’t expected to arrive until possibly the end of 2026, and it has been revealed that this installment will pick up after a time jump. So, if you start watching Rings of Power now, the year wait before the premiere of season 3 would allow for just the right amount of built anticipation.
Ultimately, joining in on the debate is all part of the fun of watching this Prime Video series.
The Lord of the Rings: The Rings of Power is among Prime Video’s most-watched original series, and it is known for its massive production budget. It truly is spectacular to behold, but it’s also become highly divisive. Rings of Power has been criticised for its changes to the canon story and has been heavily compared to Peter Jackson’s Lord of the Rings film trilogy. Ultimately, joining in on the debate is all part of the fun of watching this Prime Video series.
Good Omens
Good Omens is a fantasy comedy TV series based on the novel of the same name by Neil Gaiman and Terry Pratchett. It follows the demon Crowley and the angel Aziraphale as they discover that the apocalypse is on the way. Despite their opposing allegiances, the pair attempt to prevent Armageddon together. It’s wholly outrageous but surprisingly impactful, not to mention entertaining.
There are currently two full seasons of Good Omens on Prime Video, with a total of 12 episodes, each running about 45 to 60 minutes. Though there was initially a third season on the way, this has been adjusted to be a single 90-minute episode that will wrap up the overall series. It’s expected to arrive in 2026, making now the perfect time to catch up on the story ahead of the upcoming finale.
Good Omens has become a touchstone for comic fantasy on streaming, making it an absolute must-watch for anyone who frequents the genre. It has performed exceptionally with critics and has earned a handful of Emmy Award nominations over the years. Overall, Good Omens has made a significant cultural impact, and it’s not too late to get in on the fun.
The Legend of Vox Machina is an animated fantasy adventure series, intriguingly based on Critical Role’s first Dungeons & Dragons campaign. The series follows a band of mercenaries (Vox Machina) who begin as a bunch of misfits but evolve into genuine heroes. It’s a story that blends epic battles, dark magic, political intrigue, and inspiring character arcs, all through breathtaking animation.
This Prime Video series is made up of three seasons and 36 episodes, so it’s a very manageable binge. The Legend of Vox Machina season 4 is scheduled to premiere in 2026, and the series has been greenlit for a fifth and final installment. Now is the perfect time to binge through the existing episodes, so you will be all set for the continued story.
Not only will The Legend of Vox Machina continue into two additional seasons, but a spinoff series is already in the works. The Mighty Nein will be based on Critical Role‘s second campaign, set 20 years after the events of Vox Machina. Season 1 of this spinoff will premiere on November 19, 2025. So, bingeing The Legend of Vox Machina now means you can dive into the new series shortly after, making the wait for the next installments in this excellent Prime Video fantasy that much easier.
