Summary
In Nazi-occupied Netherlands, a young Jewish woman joins the Dutch resistance after her family is killed, going undercover by seducing a high-ranking German officer. As she navigates a dangerous web of espionage, loyalty, and betrayal, she discovers that the lines between ally and enemy are far from clear.
Black Book (2006) is a film IMDb files under the drama, thriller and war genres.
A second review pool sits behind it as well: 3,028 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. 228 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 233 reviewers with at least two reviews each feeds the raw-average track. Its in-cohort standing is measured against the other 7,846 2000s films, 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 Black Book 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 · 2000s (7,847 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 228.
