Summary
Superman takes on the cause of global nuclear disarmament after a schoolboy's plea, gathering the world's atomic weapons and hurling them into the sun. Lex Luthor exploits the situation by using stolen Kryptonian DNA to create Nuclear Man, a solar-powered foe who forces the Man of Steel into a globe-spanning battle while Clark juggles a Daily Planet takeover and a new romantic interest.
Superman IV: The Quest for Peace (1987) is a film IMDb files under the action, adventure and science-fiction genres.
3,140 other films from the 1980s form the cohort it is ranked inside. Rotten Tomatoes carries a separate audience for the same title, 2,151 of whom clear the calibration test. The calibrated figure is built from 304 reviewers whose rating history varies enough to place their own average. A broader pool of 310 reviewers with two or more reviews feeds the raw-average track instead.
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 Superman IV: The Quest for Peace 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 304.
