A worthy effort
Since there is no discussion here yet and I have just seen this doc, I will say a few words.
It is a worthy effort. It effectively paints a sad picture of dying hope for Tibet. There are several very good, very poignant scenes.
It is a bit unfortunate that it is so lacking in vibrancy. The tone is slow, gloomy - not particularly attractive to a modern audience. Even the narrator's voice can almost put you to sleep. Gloomy monotone.
I'm not saying any of that is inappropriate. On the contrary. It's just that I can picture a young person getting 15 minutes into it saying, "BOOOOOOORING!" and shutting it off.
But it is aimed at an intelligent viewer with some appreciation of subtlety I think. Within the patient, methodical delivery, there really are some very powerful scenes.
I am better informed and educated for having seen it.
