How we calculate this

These are editorial estimates of intensity, informed by reading and review evidence, then checked before publication. They aren't star ratings, reader-vote averages or a measure of quality.

Each dimension runs from 1 (low) to 5 (exceptionally intense). A 5 is reserved for strongly consistent evidence. People experience horror differently.

Scary: Fear, tension and immediate threat.
Creepy: Unease, dread and an uncanny atmosphere.
Gore: Graphic injury, blood and bodily detail.
Disturbing: Upsetting ideas and lingering psychological impact.
Weird: Surreal, strange and reality-bending elements.

We draw a filled profile only when all five scores have been reviewed. Unrated does not mean mild. Missing scores are not estimated from genre tags or your saved taste. This profile isn't a complete content-warning guide.
