Summary
An animated science-fiction anthology framed by the Loc-Nar, a glowing green orb of pure evil that recounts its corrupting influence across time and space. Segments span a hard-boiled cabbie in a future New York, a nerd transported to a barbarian world, a stranded bomber crew, a corrupt alien trial, and a sword-wielding warrior woman who confronts the orb itself, all set to a hard rock soundtrack.
Heavy Metal (1981) is a film IMDb files under the adventure, animation and fantasy genres.
The calibrated figure is built from 174 reviewers whose rating history varies enough to place their own average. A broader pool of 177 reviewers with two or more reviews feeds the raw-average track instead. 3,140 other films from the 1980s form the cohort it is ranked inside. Rotten Tomatoes carries a separate audience for the same title, 345 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 Heavy Metal 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 174.
