Summary
After scientists splice human DNA with an alien genetic code transmitted from deep space, the resulting hybrid grows into a beautiful young woman named Sil who escapes the lab and heads to Los Angeles. Driven by an overwhelming biological urge to mate and reproduce, she eludes a government team assembled to hunt her down before she can spawn a new species capable of overtaking humanity.
Released in 1995, Species is an action, horror and science-fiction film.
The calibrated figure is built from 166 reviewers whose rating history varies enough to place their own average. A broader pool of 166 reviewers with two or more reviews feeds the raw-average track instead. The cohort it is ranked inside is 1990s films — 4,082 of them. Rotten Tomatoes carries a separate audience for the same title, 1,304 of whom clear the calibration test.
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 Species 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 166.
