Hereditary presents grief as an unstoppable force passed down through family lines. After the death of a child, a family unravels emotionally and psychologically. Supernatural elements appear, but they are secondary to trauma. Each character reacts differently, yet all are manipulated by forces beyond their awareness. The cult narrative reveals that free will was an illusion from the start. Fate was inherited. The horror comes not from demons, but from the realization that personal choices were never truly one’s own.
