Summary
In the small fishing town of Noyo, California, mutated amphibious creatures emerge from the sea and begin attacking the locals. As bodies pile up and tensions rise between fishermen and the local Native American community, a marine biologist discovers the monsters are the result of experimental growth hormones contaminating the water, and they're coming ashore to breed with human women.
Humanoids from the Deep is a 1980 horror and science-fiction film.
The calibrated figure is built from 121 reviewers whose rating history varies enough to place their own average. A broader pool of 122 reviewers with two or more reviews feeds the raw-average track instead. Its in-cohort standing is measured against the other 3,140 1980s films, not against the whole corpus. Rotten Tomatoes carries a separate audience for the same title, 169 of whom clear the calibration test.
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 Humanoids from the Deep 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 121.
