The Ripper
Scored from 112 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: TV Mini Series · 2020s (1,094 peers).
Summary
A documentary series examining the crimes and investigation of Peter Manuel, a Scottish serial killer from the 1950s.
Released in 2020, The Ripper is a crime and documentary miniseries. Its country of origin is listed as the United Kingdom.
Rotten Tomatoes carries a separate audience for the same title, 4 of whom clear the calibration test. The calibrated figure is built from 112 reviewers whose rating history varies enough to place their own average. A broader pool of 115 reviewers with two or more reviews feeds the raw-average track instead. Its in-cohort standing is measured against the other 1,093 2020s miniseries, not against the whole corpus.
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 The Ripper 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 · 2020s (1,094 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 112.
