Scored from 166 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: Films · 2020s (7,930 peers).
Summary
A family of overprotected suburban mallard ducks convinces their cautious father to leave their New England pond for a migration to Jamaica. Their journey takes them through New York City and a series of misadventures involving herons, pigeons, and a parrot, pushing the sheltered Mallard family far outside their comfort zone.
Released in 2023, Migration is an adventure, animation and comedy film. Its comedy subtype is Goofy.
A second review pool sits behind it as well: 409 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. 166 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 173 reviewers with at least two reviews each feeds the raw-average track. 7,929 other films from the 2020s 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 Migration 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 · 2020s (7,930 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 166.
