There's no denying the grand effort that went into making this historical presentation of the Japanese attack on Pearl Harbor. Taking accounts of both sides of the war equally, made respectively by both United States and Japanese production crews, Tora! Tora! Tora! is a great documentation of how the attack really occurred. Unlike the recent Pearl Harbor film, which tries to tell the historical story (with many flaws), a love story and a disaster story, Tora! Tora! Tora knows what is meant to be, and strictly follows the historical angle.
Unfortunately, this dedication to fact is the films major weakness. There are no real characterizations of any of the major roles, no central character the audience can connect with, either on the American or Japanese forces. This lack of a so called staring role (which both sides should have had) makes the film feel more like a documentary then a movie. What characters the film does center on are all flat and rather uninteresting. Not to mention poorly acted.
Despite this, the film provides a great understanding of how the attack really occurred, and gives a wonderful visual feast of the disaster. For 1970, when this film was released, the visual effects are outstanding. Definitely worth at least one viewing, more if you're a World War II buff.
