When Christopher Nolan's "Dunkirk" got released, it drew controversy for omitting the Indian troops in British armed forces who were in Dunkirk. That said, it's one intense movie. It focuses on a couple of people participating in the evacuation and how their stories intertwine. Most of it is shot in a naturalistic style to increase the intensity, and there's limited dialog. There are only a few notable actors in the movie, so as to keep the focus on the story.

It's not a great movie, but worth seeing. Tom Hardy's character's flight alone is enough reason to see the movie. From what I heard, Nolan's "Interstellar" sucked, so he's made up for it. I do hope that there's eventually a movie about the Indian troops in the British armed forces, though.
