Is Grant actually good?

Grant sits in the 91.4% percentile against all 52,376 ranked seriess, meaning it scores above 91.4% of them. That figure is a rank, not a star average: each reviewer's score is re-centred on their own rating history before anything is compared, so a generous grader and a harsh one count the same.

How does Grant compare to similar seriess?

Within TV Mini Series · 2020s, Grant lands in the 87.8% percentile. The cohort comparison exists because a global rank flatters or punishes a series for its category rather than its quality.

How many reviewers is Grant's score based on?

56 reviewers cleared the calibration test for Grant — meaning their rating history varies enough to place a personal baseline. Reviewers who rate everything the same carry no information and are excluded rather than averaged in.

How is the Grant score calculated?

Every review is scored relative to the reviewer's own average rather than taken at face value, then each calibrated reviewer is weighted equally and the result is expressed as a percentile against the full corpus. The output is a rank among peers, which is why it is published as a percentile and never as a star rating.

Summary

A three-part History Channel docudrama tracing Ulysses S. Grant from an Ohio boyhood spent avoiding his father's tannery, through West Point and a stretch of civilian failure that left him selling firewood in St. Louis, to command of the Union armies. Dramatic reenactments carry the Civil War campaigns — Fort Donelson, the shock of Shiloh, the siege of Vicksburg, the grinding push toward Appomattox — while historians including Ron Chernow, whose biography informs the series, discuss Grant's tactics, his drinking and his standing among contemporaries. Later sections cover his two terms as president, the Reconstruction fights that defined them, and his final effort to complete his memoirs.

Grant is a 2020 biography, documentary and history miniseries. Its country of origin is listed as the United States.

Rotten Tomatoes carries a separate audience for the same title, 1 of whom clear the calibration test. Its in-cohort standing is measured against the other 1,093 2020s miniseries, not against the whole corpus. 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 58 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 Grant 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 Mini Series · 2020s (1,094 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.
