It’s rare for a horror movie, even the most acclaimed, to terrify the audience from start to finish, but Neil Marshall’s 2005 masterclass in horror filmmaking The Descent manages to do just that. Steeped in dread from the very opening scene, The Descent is equal parts brutal, thought-provoking, and nerve-wracking for the viewer. It follows a group of women as they embark on a spelunking expedition as a way to reconnect and distract one member of their group, Sarah, after the tragic deaths of her husband and daughter.
