Lesson of the Evil
Scored from 26 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: Films · 2010s (13,059 peers).
Summary
A charismatic high school teacher harbors dark secrets and manipulates his students for his own sinister purposes. His seemingly perfect persona masks an evil nature.
Released in 2012, Lesson of the Evil is a horror and thriller film. It plays in Japanese. Its country of origin is listed as Japan.
Only 26 of its IMDb reviewers rate with enough spread for a personal baseline to be measured, so the calibrated figure rests on a thin sample; a broader pool of 26 reviewers with at least two reviews feeds the raw-average track. 13,058 other films from the 2010s form the cohort it is ranked inside. Rotten Tomatoes carries a separate audience for the same title, 25 of whom clear the calibration test.
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 Lesson of the Evil 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 · 2010s (13,059 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 26.
