How to train your dragon

This movies synopsis
Set in the mythical world of burly Vikings and wild dragons, and based on the book by Cressida Cowell, the action comedy tells the story of Hiccup, a Viking teenager who doesn't exactly fit in with his tribe's longstanding tradition of heroic dragon slayers. Hiccup's world is turned upside down when he encounters a dragon that challenges he and his fellow Vikings to see the world from an entirely different point of view. I like the hero of this film, Hiccup.
He is brainy son of a browny Viking chief, but he is too smart to waste time feeling sorry for himself. He's going to become a Viking warrior his own way.
When he befriends his vicious enemy, an injured wild dragon, he begins double life.

I like this film, During seeing this film, I always smiling.
Hiccup is a troublemaker but he has warmhearted.
Other people(Vikings) are just killed the dragon. They think dragon is harmful for them.
I’m warmhearted too. So I understand Hiccup’s position.
Other people says Hiccup is troublemaker but I think he is a peacemaker.
Because Vikings are always fight hard with dragons.
But Hiccup become familiar with dragon.
And then Hiccup tell the Vikings dragon is not harmful.
So everyone become familiar with dragons.
And they need not fight with dragons. They are notice dragon is not harmful.
Ordinary people has a pet for example dog, cat, birds….
But Vikings are has a pet for dragons!
