Summary
DreamWorks Animation's fantasy adventure, adapted loosely from Cressida Cowell's books, is set on the windswept Viking island of Berk, where killing dragons is the measure of a man. Hiccup, the scrawny, inventive son of chief Stoick the Vast, brings down a Night Fury — the rarest and most feared dragon — with a homemade bola launcher, then finds he cannot bring himself to finish it. He instead nurses the injured animal in secret, names it Toothless, and builds it a prosthetic tail fin so it can fly again. What he learns from the dragon makes him unexpectedly good at the village's dragon-fighting school, and forces him to hide the reason from his father.

Rotten Tomatoes carries a separate audience for the same title, 13,907 of whom clear the calibration test. The calibrated figure is built from 650 reviewers whose rating history varies enough to place their own average. A broader pool of 684 reviewers with two or more reviews feeds the raw-average track instead. The cohort it is ranked inside is 2010s films — 13,059 of them.
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 How to Train Your Dragon 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 650.
