People have such poor attention spans these days- thanks to a steady diet of Marvel and other action shows that when they have to pay attention to a movie like this, they can't. This is an intelligent 'whodunnit' story ( forget comedy) that unfolds as it goes along , it just needs a little bit of patience. Christian Bale shines as the eccentric Doctor, and Margot Robbie is riveting as the Nurse. It's not a 'comedy' but does use dark humour well. There is a difference. The story of vested interests, political interference, bribery and corruption as as pointed today as they were back then. The movie also doesn't step away from how badly black people were treated in the armed forces and society in general, and it also shines a light on the the uncomfortable role the medical profession played in the suppression of so called 'hysterical' women. It's a warning about fascist dictatorships, and the price of war, that may leave many people uncomfortable. We loved it, enjoyed the dialogue and didn't find it hard to follow. Perhaps stay away if your favourite films are based on fictional superheroes.
