Query: Best Documentary I've ever seen

I watch perhaps more documentaries than is healthy, but I do tend to learn a lot. In my many years of watching I've never found a documentary as well done as this. It's entertaining and disturbing at the same time. The use of photographs and voices in this production are put together quite well and by far surpass any other production I've ever seen. I would definately recommend this to even new students of the war, although this is done well enough to impress even historians who have spent many years in study.
