Summary
A year after a tragic accident, a group of adventurous women reunite for a caving expedition in the Appalachian Mountains. When a passage collapses behind them, they discover they are trapped in an uncharted system - and that they are not alone in the dark. Tensions among the friends fracture as predatory creatures begin hunting them through the tunnels.
The Descent is a 2005 adventure, horror and thriller film.
The cohort it is ranked inside is 2000s films — 7,847 of them. A second review pool sits behind it as well: 1 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. 1,056 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 1,087 reviewers with at least two reviews each feeds the raw-average track.
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 Descent 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 1,056.
