I watched the movie years ago and it was so moving. The book is far more detailed - not just about the process of the list and all it entailed but about how Schindler got to that point of making the list - what he did with his own camp and factory in Poland before Brinnlitz, and how strategic he was to be able to get away with what he did, having the Nazi’s trust him just to subvert their own goals. 

It’s sort of an odd writing - almost in a format of short stories as it weaves in the lives of everyone in Schindler’s orbit and then later ties them together. It feels more like a nonfiction than the historical-fiction/biographical-novel that it technically is. It’s very dense but incredible learning what he accomplished saving so many people.
