Suggest grim, bleak, disturbing slice-of-life films. 1970s to present.

I recently watched the following:

In the Bedroom

Little Children

The Poker House

Dark Places

American Beauty

Taxi Driver

Midnight Cowboy

Scarecrow

What are some other films that deal with everyday people in bleak, depressing and/or dangerous situations? No cops or government agents or that sort of thing.
