The most compelling scene (spoilers)
When the store owner put the boy in front of the tv where he saw his teacher and started weeping. It was so sweet and sad at the same time, it made me watery too. And I'll never forget it when the news reporter asked the boy on the way back to the village what impressed him the most about the city and he said, "That I had to beg for food. I'll always remember that."
So compelling. So much said in so few words by a small child.
