Back in 1973, I have the opportunity to see this film in a lush big screen and back them that was an impressive show. Of course, anyone that has grown up in today's computer animated hyper realistic effects will dissect the movie mercilessly. In the other hand, we have here a film that depicts an event that 35 years later will make a good docudrama in the Discovery Channel. This drama described with precision a nation loosing his homeland to a great cataclysm that literally erase Japan out of the map, dispersing the surviving population around the globe separating families and friends to eventually live at the mercy of surrogate countries. I will love to see this film made again with today's f/x technology. Japanese filmmakers have matured well enough to create one the most shocking films ever.
