Tenebrae
Scored from 187 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: Films · 1980s (3,141 peers).
Summary
An American mystery novelist travels to Rome to promote his latest book, only to find that a killer is murdering people in ways inspired by his writing. As the bodies pile up and the police investigate, the author becomes entangled in the case and tries to uncover the identity of the murderer who seems obsessed with his work.
Released in 1982, Tenebrae is a horror, mystery and thriller film.
Its in-cohort standing is measured against the other 3,140 1980s films, not against the whole corpus. Rotten Tomatoes carries a separate audience for the same title, 518 of whom clear the calibration test. The calibrated figure is built from 187 reviewers whose rating history varies enough to place their own average. A broader pool of 190 reviewers with two or more reviews feeds the raw-average track instead.
How the score was built
We compare the reviewers of this title against every other title those same people reviewed. Each review is scored relative to the reviewer's own baseline — a 7/10 from a hard grader sits well above their average, while a 7/10 from a generous grader sits below theirs. Every reviewer then counts the same, so the result is a calibrated consensus rather than a raw average.
- Global percentile
- Where Tenebrae lands against every title we rank.
- In-cohort percentile
- The same comparison narrowed to its cohort — titles of the same format released in the same decade. A 1970s film is judged against 1970s films, not against last year's streaming series. Ranked against Films · 1980s (3,141 titles).
- AI-adjusted percentile
- The same reviewer-normalized score, corrected for how much confidence the sample supports: thin samples are pulled toward the corpus average. Each title keeps the share n / (n + 53) of its measured distance from the average, where n is its calibrated-reviewer count, and the result is ranked on the same scale as the global percentile.53 is the median sample size across everything we rank. Here n is 187.
