Scored from 1,732 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: Films · 2010s (13,059 peers).
Summary
A biologist and former soldier volunteers for a classified military mission into a mysterious expanding zone called "The Shimmer" where the laws of physics and biology behave abnormally. She must lead a team of scientists through this strange landscape to uncover what happened to her missing husband and the true nature of the phenomenon.
Annihilation is a 2018 science fiction, thriller and mystery film. It was made in the United States. Alex Garland directed it. It runs 2h 1m. It stars Natalie Portman, Jennifer Jason Leigh and Gina Rodriguez. It is rated R.
Its in-cohort standing is measured against the other 13,058 2010s films, not against the whole corpus. A second review pool sits behind it as well: 1,768 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. 1,732 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 1,803 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 Annihilation 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 1,732.
