I recently started watching a documentary found through /r/documentaries entitled "adolf hitler- the greatest story never told" and was wondering how factually correct it was as it seems to be loved by quite a few unsavoury groups. A link to the documentary. Im also a bit skeptical of some of the sources especially the website sources. Edit: The official website
Had a quick look at the website, seems like the typical revisionist "documentary". Holocaust denial, references to ethnic cleansing of germans, calling the allied leaders 'war criminals'.
You will learn no proper history from this propaganda piece.
