Nothing really scratches the itch. Ari Aster's work does pretty well but the one movie I've seen that has had my heart rate through the roof, just pants-shittingly terrified and anxious and hanging on every word and every second of the movie, was Pontypool. These others aren't horror, but Come and See (of course) and Good Time were similarly intense to what I'm looking for.

I've looked around and I've seen a handful of what other people have recommended in older posts but nothing I've seen has really done it. Pontypool has been the best horror movie I've ever seen ever since the first time I saw it and no matter how many times I watch it I'm still afraid to breathe, turning over the dialogue in my head for weeks after.

Any recommendations? Anything that's so dread inducing it makes you feel physically ill?

Edit: I've seen Green Room suggested a few times and YES, exactly that is a perfect example. I love that movie.

Edit 2: I mentioned Ari Aster in the second sentence of the post. Please stop suggesting Hereditary, Midsommar, and Beau is Afraid. They are great movies. Two of my favorite movies (and also Midsommar lol). Also I kinda thought having seen Uncut Gems was implied by the mention of Good Time as Good Time is a less well known Safdie movie. Uncut Gems was good and all but if you've only seen it, WATCH GOOD TIME. It's so good. I liked it better honestly.

But I kinda want to reel this post in. Pontypool and Green Room are the best examples within the horror genre and my god are they good. Watch Pontypool and you'll know what I mean.

And yes I'm going to watch mother! and The Coffee Table and Irréversible and Climax
