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)
Osgood “I mispelled it in the image but I’m not fixing it” Perkins: Longlegs, The Monkey (Adapted by)
Julia “Heir to the Cronenberg kingdom” Ducournau: Raw, Titane
Panos “I did it before it was cool” Cosmatos: Beyond the Black Rainbow, Mandy
Pretty good list. I love the movies by Eggers, especially VVitch, and The Lighthouse. Peele does some good stuff. One that I didn’t see anyone mention here is Talk to Me, which I enjoyed quite a lot.
Also, for non-English stuff, I’ve absolutely loved Lapachhapi, Aamis, Tumbbad, Kothanodi, and Bulbbul. Some of them might be hard to find, but totally worth it.
