Movies that maintain a consistent air of dread or tension throughout the entire runtime?

Hello,

I am searching for intense movies that feel really difficult to watch and really make a person feel tense or anxious while watching. Like the anticipation of a roller coaster climbing, waiting for the drop.

Wind River is one that comes to mind, but there was a bit of levity in it with how good the chemistry between Olsen and Renner was. I prefer something that really doesn’t let up and wants you to feel as miserable and scared as the characters do.

Basically the same atmosphere of the basement scene in Zodiac, but for 90 minutes straight. Anything that can scratch that itch?

Thanks!
