The First 48
Scored from 27 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: TV Series · 2000s (1,360 peers).
Summary
An A&E documentary series that embeds camera crews with homicide units in American cities — Miami, Memphis, Dallas, Detroit, Birmingham, Cleveland, New Orleans and others — and follows real murder investigations from the initial callout onward. Its organising premise, stated in the title and in Dion Graham's narration, is that a detective's chance of closing a case falls by roughly half if no solid lead emerges within the first forty-eight hours. Episodes typically braid two cases together, using canvass and interrogation-room footage with an on-screen clock counting down. Running since 2004, it has produced hundreds of episodes and several spin-offs.
Released in 2004, The First 48 is a crime, mystery and reality television series. It was made in the United States. It is rated TV-14. A typical episode runs 60 minutes.
Only 27 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 30 reviewers with at least two reviews feeds the raw-average track. Its in-cohort standing is measured against the other 1,359 2000s television series, not against the whole corpus.
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 First 48 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 · 2000s (1,360 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 27.
