“Hereditary” and modern Horror
For me, 2018's Hereditary marks a stark turnaround in the horror genre that really began a few years earlier with It Follows and The VVitch.
Horror, as a genre, is plagued with low effort, low quality, and high gore films. In recent history we've begun to get some real gems from the category. Which is to say, we've begun to receive high class films in place of cheap slashers, corny jump scares, and buckets of blood. Horror movies are beginning to come away from the "movie" category and fall more into the "film" one. It's a trend that I hope to see continue.
Whether you personally find things like Hereditary, It Follow, It Comes at Night, The VVitch, or Midsommar to be your particular style; it is difficult to argue that there isn't a level of quality here that is almost entirely absent from the last couple decades of horror.
