In no particular order:
Alex "Civil War" Garland: Annihilation (Adapted by), Men
Jordan "MadTV" Peele: Get Out, Nope, Us, Him
Ari "Eddington" Aster: Hereditary, Midsommar
Robert Eggers: The VVitch, The Lighthouse, Nosferatu (Adapted by)
Zach "WKUK" Cregger: Barbarian, Weapons
David "No, not THAT one" Mitchell: It Follows, Under the Silver Lake (probably more of a 70s paranoid thriller than horror)

Julia "Heir to the Cronenberg kingdom" Ducournau: Raw, Titane
Panos "I did it before it was cool" Cosmatos: Beyond the Black Rainbow, Mandy
in addition to the source material, the sound design and music and art direction for Annihilation was firing on all cylinders.
i still find myself haunted by scenes from that movie, but in like a cerebral level.
Hereditary just plain scared the fuck outta me. the whole movie, every scene gave me the creeps, and by the end it had risen to some kind of fascinated hysteria.

The bear scene made me fear cry. I have never done that ever before or since
