This is one of those treasures you unwittingly stumble across every so often. I came across the movie while browsing the PBS website. It's the story of twin infant girls in China who were adopted by different families - one from California and the other from Norway, and traces the communication and visits between the two.
I don't know that there was a deep message or lesson, but it was just fascinating to watch the two girls growing up and seeing how attached to each other they were, even though they lived so far away. Although it doesn't delve into the scientific aspects of nature vs. nurture, it also gives some insight about how much genetics and environment has to do with the development of people's personalities.
On top of that, the photography and music were excellent.
