How To Train Your Dragon

AN entertaining film with several moral tales. A young Viking boy is different, he isn't good at killing, he thinks differently to his peers and likes to read. He and his father have poor communication. For his Viking warrior father, the son is a failure and he's ashamed of him. The boy, Hiccup, cannot make his father understand what his concerns are - they have no common ground and the boy's mother is dead.
The Vikings slay dragons, which steal their herds and food. The dragons, meanwhile, are trying to assuage a hungry, mighty dragon that lives inside the dragons' island. The fighting between dragons and Vikings has been going on for 300 years.
Hiccup learns to train dragons by working with a dragon that has a misformed tail fin. He makes a prosthetic tail fin for the dragon and learns to ride him. Through learning to work with the dragon he learns how to tame other dragons and shows his peers in dragon-fighting school. He teaches them all to fly dragons.
When Hiccup's father discovers that his son's dragon, Toothless, knows the location of the dragons' island, he chains him and forces him to head for the island. The inevitable showdown (high noon at OK Corral) takes place. The dragons all fly away when the Vikings come but they Vikings have unwittingly set free the monster dragon that has been keeping the others enslaved. Only Hiccup and his peers with their flying dragons can save the day. They do but at the cost of Hiccup's foot. He too then has a prosthetic appliance attached to his leg.

Just because something has been done one way for 300 years doesn't make it right.
Even with a disability, a boy or a dragon can save the day.
Being able to see things differently can be a real help - even when it isn't popular.
A parent can learn from a child.
The enemy that you've been fighting for centuries may truly be your ally.
Defeating the enemy that you see may unleash the enemy that you cannot.
Having a "deal" where you impose your will on another is no deal at all.
Communicating isn't just about talking and talking more loudly or with accompanying loud noises doesn't make it communication.

All this - and more - from a film for children. Plus it's fun and the animation is awesome.
