Straw Dogs (1971)

The Parallax View (1974)

Dressed to Kill (1980)

Wind River (2017)

What Lies Beneath(2000)

Arlington Road (1999)

Orphan (2009)

I think the prequel comes out next month and DO NOT watch the trailer or read the synopsis of the prequel 'till you've watched Orphan or you'll get spoiled on the great plot twist of the first movie.

The Conversation

The Interview (1998)

Australian film staring Hugo Weaving from the Matrix. It really holds you on a knifes edge

LA Confidential. Tremendous movie with an incredible cast. Has a fair amount of recognition but not quite as much as some of the films you named.

Blue Ruin

Resurrection (1999)

Blood Simple, gritty first effort by the Coens

Inside Man by Spike Lee, starring Clive Owen, Denzel Washington, and Jodie Foster. Smaller in scope than the ones mentioned which might be why it's overlooked but it's tense and tight and highly regarded by the people who have seen it

The Invitation , Coherence , The Dark and the Wicked , The Autopsy of Jane Doe and His House

Invisible man! 2020, watch it at night for ideal experience

Blue Ruin, They look like people, Spring, What Josiah Saw, The Wailing

The Gift (2015)

Insomnia

Red Eye

The Cell

Dead Calm

Grizzly Man (documentary)

Bug

The Grey

The Empty Man

Red Eye. This is one you don’t hear about often, mainly because the late Wes Craven was known for being a man who made straight up horror films, like Nightmare on Elm Street (the original, not the remake). Red Eye will totally mess with your head.

Possessor

Nightcrawler

Calibre

The guilty (2018 European version), this is a great great movie

Lots of black mirror episodes, lots of love death and robots episodes

Memento

May be too tame (certainly not horror) but more of a slow burn would be "The Conversation"

It's a war movie but Full Metal Jacket (and maybe even Platoon)

Collateral (more suspense/thriller)

Silence of the lambs

Red dragon

Prisoners

Mystic river -It's a mystery/police story but very cerebral and dark, may stray too far from your request

Enemy - super abstract, don't expect a traditional story/ending

The killing of a sacred deer - fucked up and kinda abstract

These are ones I rarely see mentioned:

House of Games (1987)

The Spanish Prisoner (1997)

Trance (2013)

Backtrack (2015)

Brawl in Cell Block 99 (2017) Insanely badass prison film, who knew Vince Vaugh was a tough guy?! Great movie.

The Accountant

Headhunters

Sleepless Night

I Saw The Devil

Eastern Promises, not quite recent though

The Guest from 2014 with Dan Stevens is really good

The Changeling

Serenity (2005) - IMDb

Let the Right One In

Barbarian: 2022 movie staring Bill Skarsgard

It was a bigger release but not ever talked about - I found it gripping in the theater and saw it at home again and it was good many years later.

Breakdown (1997)

With Kurt Russel
