An unusual take on the story of the Holocaust though rather pointless.Same as the title-what is the Devils arithmetic? The film will teach you nothing about the Holocaust. As a time travel story it works to an extent in that it concludes by bringing the girl back to her own time as if its all been a dream. Obviously its full of artistic license-the Germans all speak English and it roughly follows what we already know about the ghettoes which were to lead to the camps. I don't think anyone could be unaware of what happened in Germany in the 40s but comparing this to the various documentaries on individual POW camps or classic movies like Schindlers List and its hardly in the same class. As a time travel movie its like Back to the Future or Peggy Sue got married without the music.
