Scored from 124 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: TV Mini Series · 2010s (702 peers).
Summary
Ten strangers are lured to a remote island off the Devon coast under various pretexts, only to find their mysterious host absent. As a recorded voice accuses each of them of getting away with murder, they begin to die one by one in ways echoing a nursery rhyme, forcing the survivors to confront the chilling realization that the killer is among them.
And Then There Were None (2015) is a miniseries IMDb files under the crime, drama and mystery genres.
A second review pool sits behind it as well: 23 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. Its in-cohort standing is measured against the other 701 2010s miniseries, not against the whole corpus. 124 IMDb reviewers rate with enough spread for a personal baseline to be measured, and those are the ones the calibrated score reads; a separate, broader pool of 129 reviewers with at least two reviews each feeds the raw-average track.
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 And Then There Were None 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 TV Mini Series · 2010s (702 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 124.
