Horror movies come in various flavors. There are the cerebral, where the director holds back much of the gruesomeness, understanding Alfred Hitchcock’s genius realization that the viewer is able to imagine far more darkly than the director may be allowed to go. That is much of what keeps the Hitchcock canon still in high regard. You also have the slash and burn, blood spattering gorefests which result in a hamster wheel effect of an escalating arms race of who can push the edge of the envelope furthest.
There are various subgenres and permutations, but the type of horror films that are the most appealing to me are the ones that set up a clever premise, and slowly ratchet up the edginess. The gore, if gratuitous, diminishes the finished work. Films like “28 Days” and its surprisingly successful sequel “28 Days Later” fit squarely into the category I like.
Where does “Hereditary” fit in? Somewhere in the middle.
On balance, “Hereditary” has enough twists to keep me occupied, but I did not need the gruesomeness.
