All great psychological thrillers do not receive the attention that they should be receiving. Others come so subtly, get a follower or two, and all this time they have been dwelling rent-free in your head. These ten movies and series are precisely those: little-watched, little-acknowledged, and sure to keep you glued to the screen as long as the credits are still running.
The Vanishing (1988): The Darkest Endings in Cinema

In the Criterion Channel, this masterpiece by the Dutch artist is a follow-up of a man whose girlfriend vanishes at a highway rest stop and never returns. The years he spends seeking the truth and what he finds will truly disturb you. The ending of this movie by George Sluizer is one of the most tragic in the history of thrillers.
Coherence (2013): A Slower Burn Masterpiece

MOVIE PREDICTOR via you tube
Watch on Amazon Prime Video. One night, eight friends are having a dinner party when a comet flies overhead, and reality begins to shatter in a way that is not comprehensible to anyone. It was shot virtually improvised by director James Ward Byrkit and has no script, and that makes it feel even more frightening.
The Invitation (2015): Builds Dread Scene by Scene

In the Netflix video, a man is at a dinner party at his old house, where his ex-wife and her new boyfriend are. Karyn Kusama is careful in the aspect of building the tension so that when the film opens, you feel it in your heart.
The Guilty (2018): Leaves No Room

On Netflix as well, a police dispatcher receives a distress call from a woman who he suspects has been abducted, and the rest of the story is told via dialogue. The stinging emotional punch at the close is all-encompassing and well deserved.

Cam (2018): Makes Technology a Terror

Hereditary (2018): Recalls a Second Watch

Zero Media via you tube
The first movie Ari Aster films, on Max, is a follow-up to a family that has been ruined by grief and whose darkness is increasing with every scene. Toni Collette is one of the best actresses of the decade. And watch it again and see all you have missed the first time.
Saint Maud (2019): British Horror at its Finest

FlickDirect: Trailer Vault via youtube
Showtime and the Paramount+ bundle are some of the sites where Rose Glass directed this A24 movie concerning a religious nurse whose belief turns into a threat to her life. It develops slowly to a conclusion that is truly outrageous and lingers with you even afterwards.
I’m Thinking of Ending Things (2020)

Going through Netflix, the adaptation of Charlie Kaufman tells a story of a woman who goes to the parents of her boyfriend to a remote farmhouse, where nothing is real. Odd, languid, and most disturbing. Pay all your attention, and it will remain in your days.
The Watcher (2022): Stranger Than Fiction

Warner Bros. via you tube
The Netflix limited series by Ryan Murphy is based on a true story that is hardly believable. A family relocates to their dream house and starts to receive threatening letters, which are anonymous. Naomi Watts and Bobby Cannavale are utterly believable as two individuals who start unraveling.
