I Look Better in Basic Black - S1-E28
Factual error: The American women the SS brings into camp claim to be entertainers having performed for troops. The series is allegedly set in 1942. Before June 6th, 1944 there were no allied troop concentrations in central Europe, certainly not in Germany, and very certainly none of a size and security rating the USO (or probably rather its predecessor organization, since the USO was founded in 1941 and would not have been fully operational yet) would send a troupe of female entertainers to.
Suggested correction: This is wrong. Translations all over show that the sign is not only correct, but images can be found of signs with the exact same wording in real places, with the English translation right under it.
Are you trying to tell a German national how his own language works here? Zutritt is correct. Eintritt is correct. Eingang in this context was NEVER correct since the advent of modern high German. I don't know where you propose to have seen these signs, but you definitely should check your sources, mate.
