I buy war documentary DVDs so that I gather an overview without having to do my own research. I require a level of detail between minutia and over-simplification, and I'm quite happy for the researchers to tell me what to think of the subject. In short, this DVD gives fact, summary and detail, without modern style-over-content hyperbole or bias. The documentary visual material was excellently done, and the archive footage from those earliest days of moving pictures is understandably rough and sparce, but it's still surprisingly good, and used, I felt, honestly and appropriately by the film makers. Got what I wanted, thanks.
