Luther
Scored from 281 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: TV Series · 2010s (3,236 peers).
Summary
A British crime drama following DCI John Luther, a brilliant but obsessive London detective whose deep empathy for victims and dark instincts blur the line between him and the killers he hunts. Each case pushes him further into morally compromised territory, complicated by his volatile relationship with Alice Morgan, a genius murderer who becomes his unlikely confidante.
Luther is a 2010 crime, drama and mystery television series.
Its in-cohort standing is measured against the other 3,235 2010s television series, not against the whole corpus. A second review pool sits behind it as well: 89 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. 281 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 290 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 Luther 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 Series · 2010s (3,236 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 281.
