Summary
A bright thirteen-year-old honor student in Los Angeles falls under the spell of her school's most popular and troubled girl, and rapidly spirals into a world of shoplifting, drugs, sex, and self-harm. Her overwhelmed single mother, a recovering addict, struggles to hold the family together as her daughter slips further away.
Thirteen (2003) is a film IMDb files under the drama genre.
Its in-cohort standing is measured against the other 7,846 2000s films, not against the whole corpus. The calibrated figure is built from 290 reviewers whose rating history varies enough to place their own average. A broader pool of 306 reviewers with two or more reviews feeds the raw-average track instead.
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 Thirteen 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 290.
