I'm reading Klaus Fischer's seminal work on the Nazi era, and even a capable historian, noted for rooting out even the most obscure and arcane detail, can find little in terms of Nazi art and culture to report. Culturally, the Nazi era was a drought in all medias.
Many German propaganda films were turgid miserable nonsense that even ardent nazi's found distasteful. Nazi propaganda was steeped in hatred and pseudo scientific nonsense about the strength of will, and that German 'Volk' should feel no pity or pathos for outsiders or even there own kind. As there cities were bombed to buggery few Germans cared for a night of this crap at the local fleapit.
