The TV Shows Everyone Will Be Talking About This Fall: The Biggest Upcoming Series of 2026

If you feel like there is always another series worth adding to your watchlist, you are not imagining it. The second half of 2026 is shaping up to be particularly busy, with returning favorites, new adaptations and several ambitious original shows arriving across Netflix, Apple TV, Prime Video, Disney+ and other major platforms.Some of the biggest releases are still weeks away, which makes now a good time to look ahead and decide what deserves a place on your list. Here are some of the upcoming shows worth keeping an eye on.

The Gentlemen – Season 2

Netflix is bringing back The Gentlemen for a second season in September. The series, created by Guy Ritchie, follows Eddie Horniman as he becomes increasingly involved in the criminal world after unexpectedly inheriting his family's estate.

The first season mixed crime, dark humor and fast-paced storytelling, giving the show a style that felt distinctly different from many traditional crime dramas. Season 2 is expected to continue Eddie's complicated relationship with the criminal empire surrounding him.

For viewers who enjoyed the first season, this is one of the more interesting September returns to watch.

Slow Horses – Season 6

Apple TV's Slow Horses has become one of the platform's most reliable dramas, and the sixth season is scheduled to arrive on September 16.

Gary Oldman returns as Jackson Lamb, leading the dysfunctional group of British intelligence officers stationed at Slough House. The series has built a reputation for combining espionage, dry humor and tense storytelling without relying entirely on the usual spy-thriller formula.

With another season on the way, fans can expect the familiar mix of complicated investigations and unpredictable characters.

Neagley

Prime Video is expanding the world of Reacher with Neagley, a new series centered on one of the most popular supporting characters from the franchise.

The series is scheduled to premiere on September 16. Maria Sten returns as Frances Neagley, a former military investigator who has already made an impression on Reacher viewers.

Rather than simply repeating the formula of the original series, the new show gives Neagley her own story and a chance to lead the action herself. For fans of the Reacher universe, this is one of the more notable new arrivals of September.

Monster: The Lizzie Borden Story

Netflix is returning to its Monster anthology format with a new story based around Lizzie Borden.

The series is scheduled to premiere on September 17 and will explore one of the most famous murder cases in American history.

The real-life case has remained the subject of books, documentaries and fictional adaptations for more than a century. Netflix's approach gives the story another opportunity to introduce the case to a modern audience while focusing on the people and circumstances surrounding it.

It could be an especially interesting release for viewers who enjoy crime dramas and historical mysteries.

Outlander: Blood of My Blood – Season 2

The Outlander universe is also expanding. Blood of My Blood follows the parents of Jamie Fraser and explores another generation of the Fraser family's history.

The second season is scheduled for September 18 on Starz.

While it takes place before the main Outlander storyline, the series gives longtime fans an opportunity to explore more of the family's history and the relationships that shaped later events.

MobLand – Season 2

Paramount+ is bringing back the crime drama MobLand for a second season.

The series combines organized crime, family conflict and power struggles, making it a natural choice for viewers who enjoy darker dramas.

The return is particularly interesting because the first season established several competing interests, leaving plenty of room for the story to become even more complicated.

What About the Rest of 2026?

September is only the beginning.

Later in the year, several major productions are expected to attract attention. Amazon's The Rings of Power is scheduled to return in November, while Blade Runner 2099 is also expected later in the year.

Disney+ is preparing VisionQuest, another Marvel series connected to the studio's expanding television universe. The series is currently expected in October.

There is also plenty happening outside the biggest franchises. New thrillers, dramas, comedies and adaptations are arriving throughout the autumn, giving viewers considerably more choice than simply watching the biggest names.

Why 2026 Could Be a Great Year for TVOne interesting thing about the current television landscape is the variety.

Streaming platforms are no longer relying exclusively on expensive franchise shows. Alongside superhero projects and established series, viewers are getting crime dramas, historical stories, psychological thrillers, animated shows and adaptations of popular books.

That makes the coming months particularly interesting. You might already know which major shows you want to watch, but some of the year's biggest surprises could come from series that are not yet household names.

The Bottom Line

With September approaching, there is no shortage of shows to add to your watchlist.

The Gentlemen, Slow Horses, Neagley, Monster: The Lizzie Borden Story and Outlander: Blood of My Blood are among the releases worth watching, while bigger franchise projects are waiting further down the calendar.

Release schedules can change, especially for streaming productions, so viewers should check their local platform listings before making plans.

For now, though, one thing is clear: there will be plenty to watch before 2026 comes to an end.

Editor's note: Release dates and availability can vary by country and may be changed by the respective networks or streaming services.
