It's in 3-D and it's gorgeous animation. But what really matters is the story. And it's a good one. At first it seems the main story is about a Viking colony equally distant from nowhere, which is being constantly attacked by a wide variety of marauding dragons. It's a full time job trying to keep the dragons at bay and the Viking warriors are often out on their boats hunting their wily and ferocious opponents.
But really the story is about a father and chief of the Vikings who has a young son, Hiccup, who is small and who is a slick, sarcastic talker and who doesn't take orders well, but still seeks respect from his impressive father. At first, his Father will not let his son be a warrior Viking, but later relents to have Hiccup train with the other youngsters. But the young boy gets sidetracked and instead of wanting to kill dragons, the boy befriends them and seeks to understand them.
A young and inexperienced son seeking approval of a strong father is an often-told tale. Sons often act foolishly trying to impress their fathers. And fathers often ignore the strivings of their sons. In this case, there is honor and courage on all sides and it is inspiring to watch the father and son wrestle with their relationship.
And yes, about the dragons – they ARE ferocious and talented and aggressive warriors. But their motivations are a mystery that unfolds slowly. And that's the fun of this film.
FYI – There is a Truly Moving Pictures web site where there is a listing of past Truly Moving Picture Award winners that are now either at the theater or available on video.
