How to Train Your Dragon: parents' guide

7+our pick

Best for ages 7 and up. Rated PG for sequences of intense action and some scary images, and brief mild language.

An exciting, big-hearted adventure for families with kids around 7 and up, about a scrawny Viking teen who befriends the injured dragon he was supposed to kill. Battles are frequent and loud: dragons torch the village, teens train against fire-breathing beasts in an arena, and the finale pits the heroes against a gigantic dragon. The action is bloodless, but some Vikings are hurt or killed, and the hero ends the film having lost part of his leg. Language stops at one "hell," and romance is a couple of kisses. The intense battles and that lasting injury are why we suggest 7.

What's in it

Violence

Moderate

Dragon raids set homes on fire, Vikings strike back with axes and catapults, and teens face real dragons in a training arena. A colossal dragon wrecks everything in the climax. A few minor characters are killed or maimed, without blood.

Language

Mild

One "hell" ("all hell is gonna break loose"), one "gosh," an unfinished "son of a...," a couple of butt jokes, and insults such as useless and coward.

Sex and nudity

Mild

Hiccup likes Astrid, who kisses him once on the cheek and once on the lips. A classmate tries a cheesy come-on with her, and Hiccup's father jokes about a helmet made from his late wife's breastplate.

Drinking, drugs and smoking

Mild

Adults drink from mugs in the village's great hall, with nobody shown drunk. No smoking or drugs.

Scary or intense scenes

Moderate

Night raids, a Night Fury's shriek as it pins Hiccup, and the enormous final dragon can scare young kids. Hiccup nearly drowns, he and Toothless both end up permanently injured, and his lost mother comes up in a brief, sad talk.

Worth talking about

Hiccup learns that much of what his village believed about dragons was wrong. How do fear and tradition keep people from seeing an enemy clearly?
