I'm here for the suggestions too!

Wind River, the Lioness series seasons 1-3

The taking of Deborah Logan
Is there a pilot in the airplane?
Obsession

Oculus
Oldboy(not really horror)
Talk to me

These are all horrors except of the Leslie Nielsen movie which I added it as a joke but if you want psychological and or crime.

Prisoners.
And any thriller with Jake Gyllenhaal

If you’re into K-Drama and haven’t seen it, Beyond Evil is a great series. If you want some dark, soapy, addictive fun, try The Penthouse: War in Life.

I just started the Taiwanese series Had I Not Seen the Sun and so far so good.

Mother may I .
..I'm not one for horror genres but this is more of a psychological thriller ...

The empty man.

I thought it was going to suck but it messed me up for a week or two

If you like cosmic horror or cults, this is the movie for your Saturday

The world is generally dark and twisty enough for me .. but I'm enjoying the series Your "Friends and Neighbors" which has a bit of darkness to it.
