Schindler's List: Amon Goeth in reality was actually a lot more evil than he is in the movie, but was toned down because Steven Spielberg was worried that audiences would find it unbelievable. Having read up on some details, I can see where he was coming from.
Dunkirk: Dunkirk was filmed on location, which carries with it a big problem: During the evacuation of Dunkirk, the city would've been bombed to Hell, but it's perfectly fine in the movie. However, you can't exactly bomb an inhabited city for a movie, so it's understandable, at least to me.
Battlefield 1: Hoooo boy, where to begin? Most of the weapons seen either never saw combat or were incredibly rare, the accuracy of the uniforms tends to be dicey at best, trench warfare actually happened, which it basically doesn't in-game, and so on and so forth. However, correcting most of these would make for a very boring experience, whereas keeping them makes for a very unique one.
