Gore/Splatter is a horror subgenre that specializes in depicting over-the-top violence with blood and body parts flying in every scene. When the story has more action than horror, it becomes action/splatter. You can technically call it action/horror, but we feel action/splatter is the more apt description of this particular subgenre. In terms of live-action movies, think of the works of Quentin Tarantino like Kill Bill or The Hateful Eight.
