Scored from 395 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: Films · 2020s (7,930 peers).
Summary
British intelligence officer George Woodhouse is tasked with uncovering a mole who has leaked a dangerous cyberweapon, and the prime suspect is his own wife and fellow spy, Kathryn. Over the course of a tense dinner party and the investigation that follows, George must weigh his loyalty to his marriage against his duty to his country.
Black Bag is a 2025 drama, mystery and romance film.
The cohort it is ranked inside is 2020s films — 7,930 of them. A second review pool sits behind it as well: 814 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. 395 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 409 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 Black Bag 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 · 2020s (7,930 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 395.
