Just watched MONSTER ZERO and was really impressed! The special effects really hold up well! The outer space scenes were probably the best up to that time. The story is a lot of fun and the cast is enjoyable. I have always considered MONSTER ZERO my favorite of the earth invaded movies, because of the use of Godzilla, Rodan and Ghidrah to conquer the earth. I can't wait for WAR OF THE GARGANTUAS so I can watch the original double feature.
