It was decent, but definitely not as strong as the first few Godzilla movies. Godzilla certainly fell a long way from unstoppable killing machine to dancing a jig after punching Ghidorah. The Planet X plot was pretty good and the aliens were cool at the start, but became pretty predictable by mid-film. Otherwise, the monster battle was just a retread of the last film, but without Mothra.
