Summary
Three years after a zombie virus decimates humanity, a ragtag group of survivors must transport the only known human to survive a zombie bite from New York to a research lab in California, where his antibodies may hold the key to a vaccine. Along the way, they battle hordes of undead and human threats while crossing a devastated America.
Z Nation (2014) is a television series IMDb files under the action, comedy and drama genres. Its comedy subtype is Dark Comedy.
The cohort it is ranked inside is 2010s television series — 3,236 of them. 360 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 383 reviewers with at least two reviews each feeds the raw-average track. A second review pool sits behind it as well: 108 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately.
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 Z Nation 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 TV Series · 2010s (3,236 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 360.
