The Deepest Breath
Scored from 37 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: Films · 2020s (7,930 peers).
Summary
Laura McGann's documentary follows two figures in competitive free-diving: Alessia Zecchini, an Italian who has chased depth records since childhood and sets her sights on the 100-metre mark, and Stephen Keenan, an Irishman who settled in Dahab, Egypt, and became one of the sport's most trusted safety divers. Assembled from competition footage, home video and interviews with their families and fellow divers, it lays out how athletes descend on a single breath, and how blackouts during ascent make the safety diver the last line of defence. Their paths converge in Egypt, at an attempt to cross the underwater arch of the Blue Hole.
Released in 2023, The Deepest Breath is an adventure, documentary and sport film. Its country of origin is listed as Ireland. It runs 1h 30m.
Only 37 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 42 reviewers with at least two reviews feeds the raw-average track. Rotten Tomatoes carries a separate audience for the same title, 24 of whom clear the calibration test. Its in-cohort standing is measured against the other 7,929 2020s 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 The Deepest Breath 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 · 2020s (7,930 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 37.
