Slow burn horror movies don't necessarily rely on jump scares or excessive gore, instead they slowly build the dread and terror that reaches a crescendo near the end of the film. Being able to hold an audience's attention with sheer tension is a testament to both the director and actors in the film. 1968's Rosemary's Baby will keep you glued to the screen all the way to the end. Folk horror movies tend to employ this technique as seen with the original Wicker Man from 1973. More recent examples of slow burning horror films would be Hereditary where Ari Aster uses each scene to compound the tension as we hope for a mother to find a way to stay connected with her departed daughter.
