Summary
Set in 1930s Los Angeles, this noir-tinged crime drama follows Perry Mason, a low-level private investigator and associate attorney navigating cases involving murder, corruption, and moral ambiguity. Before becoming the legendary defense attorney of popular lore, Mason struggles with poverty, personal demons, and a broken legal system, all while taking on cases that challenge his integrity and resolve.
Perry Mason (2020) is a television series IMDb files under the crime, drama and thriller genres. A typical episode runs 55 minutes. It stars Matthew Rhys, Tatiana Maslany and John Lithgow. It was created by Rolin Jones and Ron Fitzgerald. It is rated TV-MA. It was made in the United States.
451 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 479 reviewers with at least two reviews each feeds the raw-average track. A second review pool sits behind it as well: 98 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. 3,069 other television series from the 2020s form the cohort it is ranked inside.
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 Perry Mason 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 · 2020s (3,070 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 451.
