Summary
During the Ice Age, a young prehistoric hunter is separated from his tribe and must survive the harsh wilderness. He encounters a wounded wolf and the two form an unlikely bond, leading to the first domestication of the species as they journey together toward home.
Alpha (2018) is a film IMDb files under the adventure and drama genres. It is rated PG-13. Albert Hughes directed it. It stars Kodi Smit-McPhee, Jóhannes Haukur Jóhannesson and Lennie James. It was made in the United Kingdom and the United States. The runtime is 96 minutes.
A second review pool sits behind it as well: 373 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. Its in-cohort standing is measured against the other 13,058 2010s films, not against the whole corpus. 463 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 484 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 Alpha 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 · 2010s (13,059 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 463.
