Failed as a drama: better as a documentary?
I did appreciate this film for most of what it was trying to do but definitely not for some of its simplistic black-and-white depictions of German soldiers, or the suggestion that Eichmann was committing atrocities because of the sexual power that his mistress held over him.
For me the personal back story of the interrogator's family largely failed: slightly clumsy, obvious and too much of a mechanical story device mainly to break up the interrogation scenes. It was far too incidental to be considered a true insight into the life of a man who was tasked with interrogating a Nazi war criminal and the acting/depiction of Garity/the interrogator was too stoic to be convincing.
In a way this is a film, like Overlord for instance, that straddles the line between drama and documentary but not intentionally in this case. It either needed to fully commit itself as a documentary about Eichmann's trial (which still could have been depicted in the same way), or go more deeply into the life and back story of the interrogator to be a true drama.
