Summary
Charlie Babbitt, a self-centered car dealer, discovers he has an autistic brother named Raymond after their father's death. When Charlie learns that his father's estate has been left to Raymond, he impulsively takes his institutionalized brother on a cross-country road trip, initially intending to secure the inheritance. As the journey unfolds, Charlie gradually develops a genuine bond with Raymond and discovers his own capacity for compassion.
Rain Man is a 1988 drama, comedy and romance film. It is rated R. It was directed by Barry Levinson. It was made in the United States. The runtime is 133 minutes. It stars Tom Cruise, Dustin Hoffman and Valerie Golino.
Its in-cohort standing is measured against the other 3,140 1980s films, not against the whole corpus. A second review pool sits behind it as well: 9,218 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. 474 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 487 reviewers with at least two reviews each 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 Rain Man 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 · 1980s (3,141 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 474.
