The Witcher: Blood Origin
Scored from 331 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
Set 1,200 years before the world of Geralt of Rivia, this prequel miniseries follows seven outcast warriors in an ancient elven world who band together against an unstoppable empire. Their quest leads to the Conjunction of the Spheres, the cataclysmic event that merged the worlds of monsters, men, and elves.
Released in 2022, The Witcher: Blood Origin is an action, adventure and drama miniseries.
Its in-cohort standing is measured against the other 1,093 2020s miniseries, not against the whole corpus. Rotten Tomatoes carries a separate audience for the same title, 453 of whom clear the calibration test. The calibrated figure is built from 331 reviewers whose rating history varies enough to place their own average. A broader pool of 350 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 The Witcher: Blood Origin 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 331.
