The small portions of this movie that have any merit, mostly the archival footage which is in some cases quite well applied, are over shadowed by a number of glaring flaws. The narrator blatantly overlooks other widespread abuses and atrocities committed by the whole of the Japanese military, instead claiming that any injustices were simply in response to pressures from the conflict with Russia. To try and whitewash Unit 731's role as a defencive measure is historically inaccurate, and since the Philosophy of a Knife claims to be a sober look at historical events, it fails on that level. I would say while there are few other movies that focus primarily on Imperial Japan's forays into chemical and biological warfare, this one does not ear points for filling a niche void.
