Imdb comment:

Fair and impartial!, 6 March 2006
10/10

The message of this fairly well made documentary is its gift. No finger pointing. No demanding of apologies. No assignment of blame. Just a dramatic portrayal of events. Very dramatic. Some of the scenes, personal and intimate scenes, are very painful to watch but are there to illustrate a horror which is hard to imagine otherwise. I came away with the feeling that dropping the atomic bombs was a terrible thing, so terrible it is beyond comprehension, but, still, a necessary thing. However, this documentary is all about the sadness, the almost unbearable sadness, of it all. If you're trying to gain a better understanding of these events, I highly recommend this.

Kuthumi:

I got tired from waiting for an unseeded upload of this drama documentary here on Piratebay, so I found this working torrent on another site. It is not my rip, but quite good.
Total: 1h33, in 2 parts. Widescreen, good stereo sound and music.
Widescreen DVDrip 720x416, XviD
Runs well in both my DivX players.

This torrent has survived on the net since April, 2006. Thanks to the original rippers and uploaders.
