I thought it was pretty good. My only criticism is how it uses a non-linear storyline. Unless you go into the movie with some fore-knowledge of the Battle of Dunkirk, then it can be very confusing.
thats for true, it became very confusing however i did understand how the storyline went and of course i knew a big deal about the battle of Dunkirk aswell.... But god damn this movie made me cry in joy and happiness
And the old civilian man on the boat, he was outstanding!
