Marley
Scored from 34 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: Films · 2010s (13,059 peers).
Summary
Kevin Macdonald's documentary traces Bob Marley from his birth in the Jamaican hill village of Nine Mile, the son of a Black teenage mother and a mostly absent white father, through the Trench Town years when he formed the Wailers with Bunny Wailer and Peter Tosh, to his emergence as reggae's first global star. It is built from rare archival footage, concert performances and interviews with Rita Marley, his children, former bandmates and Island Records founder Chris Blackwell. Alongside the music, it covers his Rastafari faith, his many children by different women, the 1976 shooting at his Kingston home days before the Smile Jamaica concert, and the exile that followed.
Marley is a 2012 biography, documentary and music film. It is rated PG-13. The runtime is 148 minutes. It was made in the United Kingdom.
Only 34 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 35 reviewers with at least two reviews feeds the raw-average track. A second review pool sits behind it as well: 451 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. The cohort it is ranked inside is 2010s films — 13,059 of them.
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 Marley 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 34.
