Ari Aster’s feature directorial debut Hereditary is a psychological horror story that takes the audience on a wild and terrifying ride along with the Graham family. Ari Aster’s filmmaking career began with short films in the late 2000s and became widely known thanks to his 2011 short film The Strange Thing About the Johnsons. After a couple more short films, Aster made his feature-length directorial debut in 2018 with Hereditary, also written by him.

Hereditary follows the Graham family, who are grieving the death of their secretive grandmother. This begins to reveal a series of disturbing family secrets, as well as unleashing a series of sinister occurrences, including one more family tragedy. The Grahams soon learn they are no longer safe and are being watched, but the reasons behind all that are beyond what they could have ever imagined. Hereditary is not only very well-written and directed, but it also has an incredible cast full of talented and well-known actors.
