Our Planet
Scored from 180 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: TV Series · 2010s (3,236 peers).
Summary
David Attenborough narrates this eight-part Netflix documentary series, which works through the planet's major habitats in turn — frozen worlds, jungles, coastal seas, deserts and grasslands, the high seas, fresh water and forests — using footage gathered over four years in about fifty countries by much of the team behind Planet Earth. Each episode sets its wildlife photography against an account of how much of that habitat has already been lost and what is driving the loss. Sequences include walruses hauling out onto a crowded Russian beach after the sea ice retreats and orangutans in the thinning forests of Borneo. The series was produced in partnership with WWF.
Released in 2019, Our Planet is a documentary and family television series. It is rated TV-G. It was made in the United Kingdom. A typical episode runs 50 minutes.
A second review pool sits behind it as well: 28 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. 180 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 194 reviewers with at least two reviews each feeds the raw-average track. Its in-cohort standing is measured against the other 3,235 2010s television series, 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 Our Planet 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 180.
