A watered-down sequel...
We've come a long way from those rigid human characters and the black and white eerie feel of the original Godzilla. The atomic threat is still very much felt, though, but every other taboo around it has gradually taken a new, friendly shape as the previous sequels came out. Like the previous film, Godzilla vs. the Sea Monster, this is shot like a spy story on a military and scientific backdrop.
A lot of care was invested in photography and the production value is satisfying, though we've seen better. The movie looks extremely good and has a generous amount of big special effects. It makes clever use of miniatures and models to create the illusion of disaster, and makes its great monsters come to life with significant skill. This is meant for a young audience and written superficially.
Perhaps the editing should have been tighter. Any matter approached with comedy doesn't blend well and humor is no excuse for sporadic bad effects. That said, the series needed refreshment and the introduction of Godzilla’s baby provides a 45 degree turn. Godzilla is now this much closer to turning into a good guy in a mythology known for protagonizing its antagonists and vice versa.
