Summary
A man awakens from a coma to discover that a rage virus has decimated London and transformed its population into violent infected creatures. He escapes the city and joins a group of immune survivors as they journey through the devastated English countryside seeking shelter and safety.
Danny Boyle directed 28 Days Later, a horror, science-fiction and thriller film from 2002. It was made in the United Kingdom. It stars Cillian Murphy, Naomie Harris and Brendan Gleeson. It is rated R. The runtime is 113 minutes.
1,127 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 1,177 reviewers with at least two reviews each feeds the raw-average track. Its in-cohort standing is measured against the other 7,846 2000s films, not against the whole corpus. A second review pool sits behind it as well: 28,381 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 28 Days Later 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 1,127.
