Summary
A group of old friends reunite for a yacht trip, but after jumping into the ocean to swim, they realize no one lowered the ladder and they cannot climb back aboard. Stranded in open water with a baby left alone on the boat, the friends struggle against exhaustion, panic, and turning on each other as hope of rescue fades.
Released in 2006, Open Water 2: Adrift is an adventure, drama and horror film.
The calibrated figure is built from 153 reviewers whose rating history varies enough to place their own average. A broader pool of 161 reviewers with two or more reviews feeds the raw-average track instead. Its in-cohort standing is measured against the other 7,846 2000s films, not against the whole corpus. Rotten Tomatoes carries a separate audience for the same title, 680 of whom clear the calibration test.
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 Open Water 2: Adrift 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 153.
