The controversy you speak of wasn't about its inaccuracy, but more on the contrary. The book it was based on, Schindler's Ark, received a Booker Prize, which is normally reserved for fiction, while this book was non-fiction. Actually, there isn't really that much inaccurate about the movie.It is widely accepted as one of the most accurate stories about World War II, and about Schindler in particular.
There are only a few historical inaccuracies, which are really just minor. For instance, in the movie, Auschwitz is liberated only after the Nazis surrendered, while in fact Auschwitz was liberated two days before the official end of the war, on 27th January 1945, while the Nazis surrendered on 29th April 1945.As said, nothing to get excited about, you can really watch the movie, without fear of being deceived, the movie is as accurate as possible.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
