Hiccup is a teenage Viking boy living in a land, Berk, where strength is prized, tradition is sacred and battles are a way of life.As Hiccup tells us, Berk is a rugged island so far off the map that it "might as well not exist." But that hasn't kept dragons from finding their location. As long as Hiccup can remember, he and his people have fought these fire-breathing beasts.   "We're Vikings. We don't run from fights -- we start them," Hiccup says.Hiccup's father is Stoick the Vast, a giant of a man who is chief of the island. He hates dragons. As legend holds, Stoick killed a dragon when he was a baby -- tearing off its head.And Hiccup -- this scrawny artistic misfit -- is next in line to lead Berk.Unfortunately, though, Hiccup doesn't share his father's talents. For starters, he's clumsy. There's also the fact that he's not bloodthirsty like the rest of his villagers, preferring instead to invent and explore. But Hiccup's fortune is about to change. It all begins when he wounds the most feared dragon of them all -- a Night Fury -- in battle. "No one has ever killed a Night Fury," Hiccup reminds us.This wounded dragon is later found miles away by Hiccup, who discovers it has an injured tail and can no longer fly. Hiccup knows his duty is to kill it, and yet he cannot bring himself to do it. Further, Hiccup realizes that this Night Fury dragon -- a young one he names Toothless -- is not the terrifying creature he was taught to fear. Instead, this dragon is not much different than a house pet -- friendly and loyal and playful.Hiccup soon comes to a shocking conclusion: Dragons are misunderstood creatures who only fight when they're attacked.But will anyone believe him?It's all part of the new Universal live-action remake How to Train Your Dragon (PG), which stars Mason Thames as Hiccup, Gerard Butler as Stoick and Nico Parker as Hiccup's rival-turned-romantic interest. Here are three reasons families will probably enjoy it. Warning: Spoilers ahead!Photo Credit: ©Universal
