We always have to keep in mind that a Documentary, after all, can tell lies and it can tell lies because it lays claim to a form of veracity which fiction doesn't. Some of the documentaries are made just to discredit some particular person, party, organization, system etc, but most of them here on TDF are non biased, without prejudice and worth watching.
