Summary
A British period drama chronicling the lives of the aristocratic Crawley family and their domestic servants at their Yorkshire country estate in the early 20th century. Beginning with news of the Titanic disaster, which upends the estate's line of succession, the series follows the household through major historical events including World War I and the social changes of the 1920s, exploring class, tradition, and shifting times both upstairs and downstairs.
Downton Abbey is a 2010 drama and romance television series.
The calibrated figure is built from 300 reviewers whose rating history varies enough to place their own average. A broader pool of 315 reviewers with two or more reviews feeds the raw-average track instead. 3,235 other television series from the 2010s form the cohort it is ranked inside. Rotten Tomatoes carries a separate audience for the same title, 84 of whom clear the calibration test.
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 Downton Abbey 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 300.
