Book Club
Scored from 259 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: Films · 2010s (13,059 peers).
Summary
Four lifelong friends - Diane, Vivian, Sharon, and Carol - have their lives upended when they read 'Fifty Shades of Grey' for their monthly book club. The provocative novel inspires each of them to reignite romance and rethink long-standing relationships, from a widow considering a new suitor to a divorced judge navigating online dating and a long-married wife trying to spark her husband's interest.
Released in 2018, Book Club is a comedy, drama and romance film. Its comedy subtype is Dramedy.
A second review pool sits behind it as well: 283 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. 259 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 267 reviewers with at least two reviews each feeds the raw-average track. Its in-cohort standing is measured against the other 13,058 2010s films, 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 Book Club 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 259.
