I have seen this at least six times. I will likely watch it several more times. Every time I watch it, I see something new that I hadn’t noticed before. I never feel the need to skip parts, either. There is a wealth of activity going on within the village island, along with village chatter which is highly entertaining. (Try turning on the subtitles to catch more going on around the main characters.)
The story is of Hiccup, the smallest, most intellectual, and most unappreciated teen in the whole tribe, taking his place in the world of his people, and with a newly elevated stature.
The characters are well played by the actors, and that includes their full animations. The story is fabulous, and Hiccup makes a mildly stoic yet ironic underdog protagonist who has communication issues with his great Viking father. But when Hiccup is catapulted into a wild adventure with a dragon, he leads his Viking villagers into new paths no one had ever imagined before.
Hiccup and Toothless learn from each other and become fast friends. Toothless is one of my favorite characters ever. Perhaps it is because Toothless reminds me so much of a lithe graceful animal, half cat and half dog, who is part cosmic clown of cuteness and yet a fierce and lethal beast. To Hiccup, he becomes a loyal companion as they begin to rely on each other.
If you haven't see this, please consider it. It's charming and yet fiercely Norse. And though I haven't yet seen the third of this series, the second is wonderful as well. I'm an adult, and yet my favorite movies are often animated features. I find the charm of these stories to be so much nicer than the dark and darker stuff out there now. So if you enjoy animated features, and you still haven't seen this one, you may find this to be a great start to a new adventure.
