There's certainly a lot to like here, but I feel they missed the mark by not showing more of the lighter and humorous moments between the inmates and their "employers." When they do, it only serves to underline and make the tragedy more poignant. But that's nitpicking, this is a great, suspenseful drama with some wonderful performances.
Production design gives precise attention to contemporary details, and some of the German actors are excellent (some KZ inmates and a guard). Unfortunately, the sequences don't add up to an emotionally gripping story. It almost feels like a string of reenactments from a TV history docu, only without interviews or a narrator. The end is bizarrely anticlimactic.
This strikes me as an excellent film with some really fine acting. Maybe some of the scenes depicting the vulgar racism of the Nazis are now a bit hackneyed, but any movie that's filmed around this subject will have to present it, I think.
