A Good Girl's Guide to Murder
Scored from 125 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: TV Series · 2020s (3,070 peers).
Summary
A bright high school student reopens a closed case in her small town, where a popular girl was murdered by her boyfriend who then took his own life. Convinced the official story is wrong, she turns the investigation into her senior capstone project and, with the victim's brother, uncovers secrets the community would rather keep buried.
A Good Girl's Guide to Murder is a 2024 crime, drama and mystery television series.
125 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 132 reviewers with at least two reviews each feeds the raw-average track. The cohort it is ranked inside is 2020s television series — 3,070 of them.
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 A Good Girl's Guide to Murder 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 TV Series · 2020s (3,070 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 125.
