Summary
A cynical television weatherman is sent to cover the annual Groundhog Day celebration in Punxsutawney, Pennsylvania, where he becomes trapped in a time loop, forced to relive the same day repeatedly. As the loop continues, he gradually transforms from a selfish cynic into a better person through repeated interactions with the townspeople and a local producer.
Released in 1993, Groundhog Day is a comedy, romance and fantasy film. Inside comedy it is classed as Dramedy. Its country of origin is listed as the United States. Bill Murray, Andie MacDowell and Chris Elliott head the billed cast. Its certificate is PG. It runs 1h 41m. Harold Ramis directed it.
The calibrated figure is built from 771 reviewers whose rating history varies enough to place their own average. A broader pool of 810 reviewers with two or more reviews feeds the raw-average track instead. Rotten Tomatoes carries a separate audience for the same title, 13,863 of whom clear the calibration test. Its in-cohort standing is measured against the other 4,081 1990s films, not against the whole corpus.
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 Groundhog Day 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 · 1990s (4,082 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 771.
