Summary
A medical drama following surgical interns, residents, and attendings at Seattle Grace Hospital. The series centers on Meredith Grey and her colleagues as they navigate complex surgical cases, personal relationships, and their careers in medicine.
Released in 2005, Grey's Anatomy is a medical drama and drama television series. Its country of origin is listed as the United States. Ellen Pompeo, Sandra Oh and Katherine Heigl head the billed cast. Episodes run about 43m. Shonda Rhimes created it. Its certificate is TV-14.
Its in-cohort standing is measured against the other 1,359 2000s television series, not against the whole corpus. The calibrated figure is built from 490 reviewers whose rating history varies enough to place their own average. A broader pool of 543 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 Grey's Anatomy 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 490.
