This a very fun movie that also had some surprising depth, especially for a summer kids movie. Just like Despicable Me and Toy Story 3, what a great summer for animated movies.
Hiccup is a teenage Viking from the island of Berk, where fighting dragons is a way of life. Hiccup's progressive views and weird sense of humor make him a misfit, despite the fact that his father (Gerard Butler) is the tribal chief. Tossed into dragon-fighting school, Hiccup endeavors to finally prove himself as a true Viking, but when he befriends an injured dragon, he has the chance to plot a new course for his tribe's future.
This film really brings it. It is funny, exciting, and tender. The animation is very good. The script and voice talent, also very good. I thoroughly enjoyed myself. Check it out with or without kids.
