A harrowing view of hell on earth, and an absolute tragedy. The film is wisely very critical of Japanese militarism with its own atrocities, fanaticism, and reaction in the aftermath of Hiroshima before a second bomb was dropped on Nagasaki. The moments when the devastated people are walking around like zombies trying to get food and the official is shouting nationalistic garbage at them are brilliant. The film also asks the question whether this target, with so many civilians, was necessary, and whether it had something to do with race. It also has strong messages for peace, to avoid such events in the future, since the Atomic age had begun. Whatever your beliefs are for whether the bombs were necessary or not (there are some amazing summaries of both positions on Wikipedia btw), the human suffering is undeniable, and heartbreaking. Even if it makes for 105 brutally sad minutes, this film is as important today as it was in 1953.
