Summary
An afflicted family relocates to Los Angeles and moves into the notorious Murder House, a Victorian mansion with a sinister past. As they attempt to rebuild their lives, they discover the house is inhabited by the vengeful spirits of its former victims and perpetrators, who are bound to the property and compelled to relive their darkest moments.
American Horror Story (2011) is a television series IMDb files under the horror, drama and thriller genres. A typical episode runs 42 minutes. Ryan Murphy and Brad Falchuk created it, with Sarah Paulson, Evan Peters and Jessica Lange in the cast. It was made in the United States. It is rated TV-MA.
743 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 793 reviewers with at least two reviews each feeds the raw-average track. 3,235 other television series from the 2010s form the cohort it is ranked inside. A second review pool sits behind it as well: 1,526 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately.
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 American Horror Story 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 · 2010s (3,236 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 743.
