AKA Godzilla vs Monster Zero.
This is the one with the dorky inventor who develops that loud alarm and the two-man spaceship that travels to a weird hidden planet ravaged by Ghidorah. That one. You remember?
There’s not a lot to recommend this movie. It’s not charming. It’s not AS bad as some of the dregs of the Godzilla series, but it’s on the way there. The double-cross by the Planet X adds a little something, but overall the most interesting scenes are Godzilla and Rodan battling Ghidorah.
For completists only.
