Thank you. It seems your name is Japanese. I'm a Jap.
I watched Citizenfour in the next day of release, in 2016. If I remember
correctly, the day of release in the West was in 2013.
And there were just about 20 peoples in the cinema. And I have watched the
DVD, and read maybe the snowden file.
This would wanders away a bit, I like Mr. Snowden's courage and intelligence,
I think he did decisive work, but although my information about it is not
plenty, I don't understand why he left his family and his girlfriend behind
when he went to HongKong. That looked there was some risk, especially there
is USA. Did he let them move to a better safe place before he open his face
to the media? I can't remember well.

But then, I would like to listen to your opinion for that too.
