Marrowbone is a deeply psychological horror movie that considers heavy ideas of memory and loneliness all explained through a careful metaphor that director Sergio G. Snchez inlays throughout his film. A 2017 English-language Spanish psychological horror, Marrowbone stars an incredible cast including pre-mega-fame Anya Taylor-Joy and Mia Goth, as well as George MacKay and Charlie Heaton. The film was received fairly lukewarmly, with a 49% on Rotten Tomatoes. What it lacks in emotional depth of its characters and originality it makes up for with its cast, atmosphere, and moving story.
