Gamera 3: Revenge of Iris
Scored from 49 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: Films · 1990s (4,082 peers).
Summary
Ayana Hirasaka, a teenage girl orphaned when Gamera's battle with the Gyaos flattened her town, discovers an egg in a cave beneath a village shrine sealed by local legend. She raises the hatchling in secret, names it Iris after her dead cat, and feeds it on her own blood and hatred so it will grow strong enough to kill Gamera. As Gyaos flocks resurge worldwide and investigators — including ornithologist Mayumi Nagamine and Asagi Kusanagi, once psychically bonded to Gamera — trace the outbreak, Iris matures into a monster fused to Ayana's grief. Shusuke Kaneko's film closes the Heisei Gamera trilogy, opening with the levelling of Shibuya and building toward a confrontation in Kyoto.
Released in 1999, Gamera 3: Revenge of Iris is an action, drama and fantasy film. It plays in Japanese. It runs 1h 48m. Its country of origin is listed as Japan.
Only 49 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 50 reviewers with at least two reviews feeds the raw-average track. 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 Gamera 3: Revenge of Iris 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 49.
