"While slashers and body horror will always remain key elements of the horror genre, some of the scariest movies ever rely on suspense to deliver the chills, not gore. A truly great horror film, gory or not, builds tension over its runtime to maximize the impact of the scares when they do come. Immersing the audience in an unsettling atmosphere, shocking them with disturbing imagery, and leaving the monster in the shadows all help to create the suspense necessary to make the big jump scare hit home. The horror genre's roots lie in suspense, in fact. Before movies began to show excessive gore, slow-burn tension was the main source of scariness. Improved effects, incredible acting and a promising new crop of horror writers and directors have all helped suspense re-establish its hold on the genre. Here are 12 great horror films that rely on suspense, not gore, including some of the best horror movies of all time." - screenrant.com
