Review by Ty Burr (3 stars)

“The key that a dog holds to unlocking something inside a person is enormous,” someone says in “Folktales,” and if that doesn’t sell you on the movie, I don’t know what will. In fact, if I had a quibble with Heidi Ewing and Rachel Grady’s moving documentary about teenagers in an Outward Bound-style program in Norway, it’s that there’s a lot about the people but not quite enough about the dogs.
