Summary
In a sleek, self-contained luxury apartment complex on an island near Montreal, a scientist's experiment with a parasitic organism intended to replace failing human organs goes catastrophically wrong. The slug-like parasites, which provoke uncontrollable sexual and violent urges in their hosts, spread rapidly from tenant to tenant, turning the building's residents into frenzied carriers. David Cronenberg's debut feature builds dread as a lone doctor tries to contain the outbreak.

The calibrated figure is built from 140 reviewers whose rating history varies enough to place their own average. A broader pool of 141 reviewers with two or more reviews feeds the raw-average track instead. Its in-cohort standing is measured against the other 2,405 1970s 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 Shivers 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 · 1970s (2,406 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 140.
