Having not read the source material, my reaction is to call this a failed adaptation. In a novel the Big Themes would come off better than the horribly awkwardness of them on screen. Speaking of awkward, I didn't buy a single one of the character relationships. Strange depiction of drug use.
I totally get it if you don't think you need to see yet another film about the Holocaust, but this one genuinely has some new things to say. The subjects really grapple with what is trying to be accomplished with war crimes trials. Emotional, but also very thought provoking.
