I saw Dunkirk on Sunday afternoon, it was a 4pm show. Maybe that time had something to do with the audience being almost all 50+, that caught my attention as soon as we walked in to take our seats. Maybe younger couples don't go to movies as much?
It was a good movie, I like how Nolan worked the timeline. He could have shown some of the fighting taking place on the lines but it seemed that his sole intention was to capture the despair from the beach. 8/10 for me.
