It's officially October, so it's only fitting that streamers like Paramount+ would add a slew of new horror movies to its library. But which ones are worth watching? To help you select the right ones, Watch With Us used Rotten Tomatoes' critical Tomatometer to determine what you should stream. The Fly and In Fabric are two horror movies that have critical scores north of 90 percent. Martin Scorsese's religious epic Silence isn't a horror movie, but it has a good enough score to warrant a place on this list. 'The Fly' (1986) Rotten Tomatoes score: 93 percent The Substance made body horror mainstream in 2024, but the subgenre has been thriving for decades. One of its founders is David Cronenberg, who directed the '70s schlockers Shivers and Rabid. He had his biggest commercial hit with 1986's The Fly, an imaginative remake of the 1958 classic starring Vincent Price. 9 New Movies to Watch This Weekend on Netflix, Prime Video and More (Oct. 10-12) In this iteration, Jeff Goldblum stars as Seth Brundle, a kooky scientist obsessed with teleportation. He builds a device that allows him to transfer organic matter from one space to another. When Seth tries it out on himself, he's successful. But when he discovers a fly was in the device with him when he teleported, Seth soon begins to experience strange physical symptoms like super strength and an intense craving for sugar. Is Seth turning into a fly? Or is it all in his head? Featuring state-of-the-art makeup that still makes you want to vomit, The Fly is gross-out horror at its finest. It also features Goldblum's best performance ever as a man who has to come to terms with his own body's limitations - and mutations. His Seth is brainy, romantic and - in the end - tragic, which makes the horror he experiences all the more effective. 'In Fabric' (2018) Rotten Tomatoes score: 92 percent There have been horror movies about killer dolls, so why not one about a deadly red dress? That's the simple but effective premise behind In Fabric, a little-seen British horror movie that chronicles all the unfortunate accidents that occur to the dress' owners. One of them, Shelia (Marianne Jean-Baptiste), is a desperate divorcee who buys the garment to impress her new date. Little does she know that it sets off a chain of events that leads to someone getting killed by a car, a death by carbon monoxide poisoning and a raging fire. Is the dress to blame? And if so, why? In Fabric is like an old horror movie anthology from the 1970s that is more episodic than your average straightforward movie. The film doesn't bother to explain how or why this dress is cursed. Instead, it shows the bloody effects it has on the people who are unfortunate enough to wear it. If the Devil truly wears Prada, it would resemble the killer dress at the center of In Fabric. 'Silence' (2016) Rotten Tomatoes score: 83 percent If I asked you what the best Martin Scorsese movie was that was made in the last 30 years, you probably wouldn't answer with Silence. The 2016 movie, about two Portuguese Jesuit priests who travel to 17th-century Japan to find their missing colleague, was a big box office disappointment when it was released. It's not hard to understand why - this 161-minute epic is demanding and often unforgiving, but it's also beautiful and unforgettable. It's one of the few films to really showcase the power of faith without being preachy or melodramatic. 8 Must-Watch Movies on Paramount+ Right Now (October 2025) Andrew Garfield stars as Sebastiao Rodrigues, one of the Jesuits looking for his mentor, Cristovao Ferreira (Liam Neeson). While in Japan, he encounters a feudal society that's hostile to him and Christianity. As Rodrigues witnesses unspeakable acts of torture and cruelty inflicted on his fellow priests, can he hold onto his faith while also locating the missing Ferreria? Andrew Garfield in Silence Kerry Brown/(C)Paramount Pictures/courtesy Everett Collection At the 2017 Oscars, Garfield was nominated for Best Actor for Hacksaw Ridge, but should've been nominated for his empathetic, devastating performance in Silence. Appearing in most scenes, Garfield is the film's central body and soul, and he successfully conveys Scorsese's complicated yet passionate feelings toward organized religion.
