This is one of the better non-Godzilla films from the minds of Honda, Tanaka, Tsubaraya and Ifukube. Even though this film pretty much covers the same ground as they did in the Mysterians (even using some stock footage from that film), it still was a great film. The special effect's work by Tsubaraya has to rank as some of his best and the story is better than average for this type of film. I loved how they pretty much showed how tortured Jinguji was as he was torn between his loyalty to Japan, his love for his daughter and the needs of the world as they were being attacked by the Mu Empire. Also, in an interesting bit of casting, Akihiko Hirata and Kenji Sahara play villains instead of their normal heroic roles. It also was interesting that the threat to Earth in this film didn't come outer space but from beneath the ocean by one of the most legendary lost civilizations after Atlantis. This is definitely a great film.
