The best I can say is that this gets people talking/thinking about Auschwitz and the Holocaust. That is why 2 stars, not one.
I have no idea if the intentions of Uwe Boll were noble. It doesn't feel to me like he was trying to be exploitative. I'll give him the benefit of the doubt.
I'm not sure attempting to show the true horror of Auschwitz in this way is useful or necessary. Either way, if this is the best you can manage as "realistic" and suggest as coming anywhere close to the true horror of Auschwitz you should not have bothered.
Nothing looks or feels right. The trains are not dark enough or packed enough. All the buildings are totally wrong. I could go on and on and on.......
Admittedly budget probably prevented giving any idea of the true scale of the industrial conveyor belt of death that occurred at Auschwitz, but given that why not zoom in and follow one or two people as individuals with much narrower focus? Or better still just stick with the interviews of german teens along with some of the facts and archive images.
The interviews and, for the most part, stunning lack of knowledge about the holocaust are the only compelling parts. The problem is I'm not convinced by this film that Uwe Boll's knowledge of this part of history is much better than the majority of interviewees.
Something like Son Of Saul is far more effective at achieving what Uwe Boll claims to have wanted to achieve.
