20th Century Girl
Scored from 57 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: Films · 2020s (7,930 peers).
Summary
A coming-of-age romance set in 1980s South Korea following a high school girl navigating friendship, family expectations, and first love during her final year of secondary school.
20th Century Girl is a 2022 drama and romance film. It runs 1h 44m. Its certificate is PG. It plays in Korean. Its country of origin is listed as South Korea.
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 61 reviewers with at least two reviews feeds the raw-average track. Its in-cohort standing is measured against the other 7,929 2020s films, not against the whole corpus. Rotten Tomatoes carries a separate audience for the same title, 2 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 20th Century Girl 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 57.
