I am a horror fan. And I realize that not all horror is jump scares, and slash and gore. And I am happy that there is variety. And what people call a slow burn, well sometimes, that build up works perfectly, as in this case. I would have rated Hereditary 10/10 or 5/5, whichever scale you prefer. I saw it while out of state, at the movies, and then rented it at a later date at home. The imagery was vivid. Toni Colette was awesome. Gabrielle Byrne, Alex Wolff, Milly Shapiro, all did an excellent job. Milly Shapiro's character was unique. I do not want to put in any spoilers, but there were some scenes that were indeed scary, shocking, and unforgettable. It is a movie that works as a psychological thriller like the Witch, or Goodnight Mommy. Loved this movie ! Also, I love classics like Rosemary's Baby, and the Shining, too. Have plenty of popcorn when you watch Hereditary ! I believe the intensity of this movie and the interesting characters, will make it an immersive experience, and memorable long after it has ended.
