Summary
Set roughly a century after the events of Vikings, this Netflix series follows a new generation of legendary Norse figures - Leif Eriksson, his sister Freydis, and the ambitious Harald Sigurdsson - as they navigate the violent collision between pagan and Christian Vikings and pursue conquest across England and beyond. Political intrigue, faith, and warfare drive their fates as the Viking age nears its end.
Vikings: Valhalla is a 2022 action, adventure and drama television series.
3,069 other television series from the 2020s form the cohort it is ranked inside. A second review pool sits behind it as well: 212 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. 483 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 536 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 Vikings: Valhalla 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 · 2020s (3,070 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 483.
