Summary
A centuries-old war rages between aristocratic vampires and feral werewolves known as Lycans. Selene, an elite vampire warrior called a Death Dealer, becomes entangled with Michael, a human the Lycans are inexplicably hunting. As she digs into why, she uncovers a buried conspiracy that threatens to upend everything she believed about her own coven.
Underworld is a 2003 action, fantasy and thriller film.
A second review pool sits behind it as well: 19,678 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. 557 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 586 reviewers with at least two reviews each feeds the raw-average track. 7,846 other films from the 2000s form the cohort it is ranked inside.
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 Underworld 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 557.
