Our 15 scariest
The Exorcist (1973)
Possession, a child and a mother's helplessness. Nothing has topped it.
Sinister (2012)
Heart monitors keep picking this one. Those home movies are the reason.
Hereditary (2018)
The scariest film of the 21st century by fan vote.
Host (2020)
A Zoom call at night. Watch it alone, on a laptop, if you dare.
The Conjuring (2013)
The clap scene alone earns its place.
Insidious (2010)
Home of the most famous jump scare of the 2010s. See Insidious in order.
The Shining (1980)
Fear as atmosphere. The hotel never lets you leave.
Skinamarink (2022)
Grainy darkness and a child's-eye nightmare. Divisive, and genuinely frightening.
The Texas Chain Saw Massacre (1974)
It feels real, which is worse.
The Ring (2002)
Seven days. Then see the original, Ringu.
Smile (2022)
Smile 2 placed too. Parker Finn knows how to stage a grin.
Halloween (1978)
The Shape in the background of every shot.
Talk to Me (2023)
The most physically shocking film here.
The Wailing (2016)
Not on either list, and it should be. Dread that builds for two and a half hours.
Hokum (2026)
The newest film here. The honeymoon suite is off limits.
