Netflix is bringing the goods this September. Whatever you're interested in, there's bound to be something for you in our complete list of what's new on Netflix this month..

Hankering for a horror? Haunting of Hill House creator Mike Flanagan is bringing the scares once more with Midnight Mass. Judging by his previous works, it's going to be a series that will live long in the memory. Maybe keep the lights on, eh?

Sex Education is also back for another season, while Netflix's answer to John Wick, Kate, is going out all guns blazing in September. Then, there's your usual sprinkling of top-quality programming to make sure you have something to binge every single week.

Sports fans are covered with the new documentary Schumacher, covering the legendary German's F1 career. There's also plenty of true crime to get under your skin, as well as one of the final parts of La Casa de Papel (AKA Money Heist, AKA the show everyone tells you to watch but you haven't got round to yet). So, get out your Notes app and start jotting down what's new on Netflix in September. Plan ahead and you'll never be stuck for things to watch. Trust us.

Kate – September 10

We all love a good John Wick clone. The assassin-turned-revenger sub-genre is booming right now, and Kate looks to be the pick of the bunch.

Mary Elizabeth Winstead stars as Kate, an assassin given a lethal dose of poison. With only 24 hours to live, she must complete one final job and navigate a city filled with bright lights and those out to kill her. It's stylish, action-packed, and Winstead stands on her own two feet as a bonafide action hero. You can check out the trailer here.

Sex Education season 3 – September 17

Sex! Now that I have your attention, Sex Education season 3 is coming to Netflix and it's all change in the hormone-fuelled drama.

Not only is there a bit of a time jump this year, but Moordale has undergone a bit of a rebrand. That even includes a new headmistress, Hope, and some other fresh faces, including Jason Isaacs as Mr. Groff's older brother, Peter.

Expect more hard-hitting storylines, sexual faux pas, and plenty of scenes that you won't want your parents walking in on later this month.

Midnight Mass – September 24

There aren't many better at making us retreat behind the sofa than Haunting of Hill House creator Mike Flanagan. 

The prolific horror director is back with Midnight Mass, a series that focuses on some shady goings-on in the isolated community of Crockett Island. After a priest rolls into town, it's clear that there are many, many secrets just hiding out of sight. 

If the first trailer is any indication, Midnight Mass is going to be a delightfully creepy tour-de-force that'll burrow into our brain and won't let go until Mike Flanagan conjures up another slice of scare-filled suspense.

I'm the Entertainment Writer here at GamesRadar+, focusing on news, features, and interviews with some of the biggest names in film and TV. On-site, you'll find me marveling at Marvel and providing analysis and room temperature takes on the newest films, Star Wars and, of course, anime. Outside of GR, I love getting lost in a good 100-hour JRPG, Warzone, and kicking back on the (virtual) field with Football Manager. My work has also been featured in OPM, FourFourTwo, and Game Revolution.
