This must be some school project or something, 'cause it's one of the worst documentaries ever made. First, the editing and direction, awful! The survivors try to tell their stories, but they keep cutting it like they only tell punchlines. The music is straight out of b-horror movie and it doesn't fit at all, anywhere, and it also cuts all the time and occasionally there are some weird synth string build ups. Why? Also, some stories are told with fixed text on the bottom and some are scrolling on the bottom, with different font of course.
But what makes this even worse, is the American voice over. Pronounciations of places and names are grade F, and that means failure. Then there is the thing, where he "acts" these stories out, and it's like watching a documentary made for a South Park episode. Around 29mins in, he says "guinea pigs" like he was Randy March and it goes on and on with that horrible b-movie soundtrack.
There's loads of documentaries about WW2 and about the atrocities of Nazi Germany, but this so called "documentary" is just plain wrong on so many levels. It doesn't do justice to the victims, quite the opposite actually, 'cause it doesn't tell a single story in full and it's made like bad school project. Clip-cut-paste-add music-do a bad voice over, it almost feel like taking advantage of history and try to cash in.
Don't watch this! It's not educational at all and it's vary badly made, with some horrifying archive footage that we have seen in so many documentaries before.
