Summary
In the small Australian fishing town of Berkeley, a meteor shower turns most of the residents into flesh-eating zombies. A small band of survivors, led by a reclusive gun-toting fisherman and a former beauty queen, barricade themselves and try to escape the outbreak while strange phenomena hint at a larger alien force at work.
Released in 2003, Undead is an action, comedy and fantasy film. Inside comedy it is classed as Action Comedy.
The calibrated figure is built from 158 reviewers whose rating history varies enough to place their own average. A broader pool of 158 reviewers with two or more reviews feeds the raw-average track instead. Rotten Tomatoes carries a separate audience for the same title, 972 of whom clear the calibration test. The cohort it is ranked inside is 2000s films — 7,847 of them.
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 Undead 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 · 2000s (7,847 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 158.
