Summary
A gothic horror film adaptation from the Dark Shadows television series, involving supernatural mysteries and vampiric elements.
House of Dark Shadows (1970) is a film IMDb files under the drama, fantasy and horror genres. It runs 1h 37m. Its country of origin is listed as the United States.
The cohort it is ranked inside is 1970s films — 2,406 of them. Rotten Tomatoes carries a separate audience for the same title, 83 of whom clear the calibration test. Only 56 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 57 reviewers with at least two reviews feeds the raw-average track.
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 House of Dark Shadows 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 Films · 1970s (2,406 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 56.
