Summary
Sam and Dean Winchester crisscross the back roads of the United States in a 1967 Chevrolet Impala, hunting the demons, ghosts and monsters most people refuse to believe in. Both were raised as hunters by their father John after a demon killed their mother Mary in Sam's nursery; Sam broke away for law school at Stanford, until Dean turns up to tell him their father has vanished on a hunt. The brothers work a case-of-the-week structure that gradually exposes a larger design behind their family's losses and their own inheritance. The series is an American dark-fantasy horror drama that ran fifteen seasons on The WB and The CW.
Supernatural is a 2005 drama, fantasy and horror television series. A typical episode runs 44 minutes. It is rated TV-14. It was made in the United States.
A second review pool sits behind it as well: 429 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. 809 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 966 reviewers with at least two reviews each feeds the raw-average track. The cohort it is ranked inside is 2000s television series — 1,360 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 Supernatural 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 809.
