The Blob
Scored from 219 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: Films · 1980s (3,141 peers).
Summary
A gelatinous extraterrestrial organism crashes to Earth near a small Colorado town and begins consuming residents, growing larger with every victim. A teenage delinquent and a cheerleader try to convince skeptical authorities of the threat, only to discover the creature's origin involves a sinister government cover-up.
The Blob is a 1988 horror, science-fiction and thriller film.
The cohort it is ranked inside is 1980s films — 3,141 of them. 219 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 220 reviewers with at least two reviews each feeds the raw-average track. A second review pool sits behind it as well: 1,844 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately.
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 The Blob 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 · 1980s (3,141 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 219.
