Seems Japanesse,Korean,Thai film not Iranian. Spoiler

Great and well-made film.

But if i didnt know that it was Iranian i would say that it was from Japan or Korea or Thailand.

Why?

Because of the way Nature takes part in the story. I mean, when the father of the boy have doubts about leting him lost or die, the weird birds singing in the dark thrilling forests. Its gives you a shaking and scary feeling. I believe these pictures are part of East-cinema because of their beliefs about the spirits of the forest and also because these forests are mostly part of their flora.

Weird and beautiful film istead
