Scored from 57 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: Films · 2000s (7,847 peers).
Summary
A fisherman discovers a mysterious woman in his nets who may be a water spirit or selkie. As he becomes captivated by her, he finds himself drawn into a world where the boundary between reality and myth dissolves, with tragic consequences.
Released in 2009, Ondine is a drama, mystery and romance film. Its country of origin is listed as Ireland. It runs 1h 49m and carries a PG-13 certificate.
Rotten Tomatoes carries a separate audience for the same title, 663 of whom clear the calibration test. Only 57 of its IMDb reviewers rate with enough spread for a personal baseline to be measured, so the calibrated figure rests on a thin sample; a broader pool of 59 reviewers with at least two reviews feeds the raw-average track. Its in-cohort standing is measured against the other 7,846 2000s films, not against the whole corpus.
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 Ondine 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 57.
