Scored from 85 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: TV Mini Series · 2000s (259 peers).
Summary
An eleven-part BBC series that gives each episode to a single habitat — mountains, fresh water, caves, deserts, ice worlds, great plains, jungles, shallow seas, seasonal forests and the deep ocean — and tracks the animals that survive there through a year of scarcity and plenty. It was the first natural history series of its scale shot entirely in high definition, using gyro-stabilised aerial cameras and long remote camps for sequences such as a snow leopard hunting on a Pakistani cliff and African wild dogs coordinating a chase filmed from the air. David Attenborough narrates the British broadcast and Sigourney Weaver the American edit; each episode closes with a short 'Planet Earth Diaries' film on how one sequence was obtained.
Planet Earth (2006) is a miniseries IMDb files under the documentary and family genres. It was made in the United Kingdom. A typical episode runs 50 minutes.
Only 85 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 90 reviewers with at least two reviews feeds the raw-average track. A second review pool sits behind it as well: 2 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. 258 other miniseries from the 2000s form the cohort it is ranked inside.
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 Planet Earth 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 Mini Series · 2000s (259 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 85.
