Godzilla Vs Monster Zero

Some astronauts(two to be specific...one of which is Nick Adams) leave planet Earth and fly to planet X. Once there, they discover life underground that supposedly lives in fear of King Ghidorah. They ask Earth to send Rodan and Godzilla to their planet to fight Ghidorah. Earth agrees, and the aliens send a tape back with the astronauts after their second voyage that tells Earthlings to submit to the alien will, or King Ghidorah, really their own private monster, will destroy them. This is an interesting film in the Godzilla series that has some pretty good sci-fi elements blended with good ole Godzilla fun. The monsters are what you would expect and the acting is pretty pedestrian as a rule. Adams is an unwelcome addition as his acting ability is somewhat suspect, and he tends to stick out like a sore thumb. Nevertheless, the film zips along at a nice pace. My only major criticism is that the monsters, and in particular Godzilla, have too few scenes. Inshiro Hondo directed this one, and it has many of his distinctive touches.
