This film is about the Pearl Harbor incident, but from the Japanese perspective. It is an older film, with subtitles. This is an enjoyable movie experience in that it is unique to the western audience. It is a representation of the Japanese sensibility, as much of a sensibility as possible when dealing with war. Much like the Clint Eastwood movie of Letters from Iwo Jima, Tora Tora Tora allows movie viewers into the thoughts of the soldiers who fought the battle. They were not portrayed as heartless killers or crazed Kamikaze soldiers who had no thoughts. The Japanese soldiers were portrayed as real people who were hesitant in engaging in any battle. They knew that war was not an answer to peace but the had to follow Imperial edict as part of their duty.
Slow by today's standards of story telling, the film is memorable and has a lasting impact on its viewers. It offers a fresh point of view for a film done in 1970. Though it is a dramitization, it has elements of actual history. Sometimes it is hard to discern the fact from the entertainment, but I guess that is what makes a movie engaging.
