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.
