The biggest strength of this film is the extreme contrast between the story of the Höss family and the story taking place on the other side of the wall. The former gets most of the attention, with the movie playing out like a slice-of-life family drama. But the latter, which exists only in the background, unspoken and off screen for most of the film, is what packs the punch. The writers leverage the knowledge that most audiences already have - we all know what was happening. And that's where the contrast is - watching a man help orchestrate one of humanity's darkest moments without any acknowledgement is disturbingly compelling. That said, this isn't my favorite kind of film, as it feels less focused on building a narrative arc and more focused on the thematic ideas. Just a little too arthouse for my tastes.
