I saw it yesterday; came away a bit disappointed.
I have noticed a lot of reviews from people expecting to see Schindler's List or something like it. And if that is what you are looking for save your self the price of a ticket.
It is a Godzilla movie. There are going to be holes in the plot and unbelievable things happen. You are supposed to suspend your disbelief and enjoy what I think was a very good sci fi movie.
I didn't expect something very deep; I knew going in it was a Godzilla movie.
For a summer action movie, it didn't have much action. Sure, you get the monster fights, but before the end, they literally tease you- they start to show, but cut away. Other "action" is footage of military; guns with guns, naval ships, helicopters. Most of the time the recruitment ads on TV have more action than those.
The prologue or whatever (1999) isn't interesting. We get introduced to an engineer on his birthday, the nuclear power plant has a mysterious disaster... and we "know" it's from monsters only because it's a monster movie. We don't learn anything, even to tease.
There's too much unbelievable stuff regarding the human characters. Example- I get that the lead is a military guy, and that they can sometimes catch rides on transports. I seriously doubt someone on leave will get to hop onto a train carrying a nuclear weapon during an international crisis.
Or the father; he appeared to be the senior engineer at the nuclear plant. So he's allowed to fall off the face of the earth for 15 years, overlooked by the secret agency, never interviewed or questioned. Then he's arrested (twice) for trespassing in the quarantine zone, and during the second time, the agency's chief scientist then randomly decides his knowledge and info are vital.
Regarding that: what is said info? We don't know, he dies.
Back to the lead actor again- so a military IED disposal tech, arrested in Japan while on leave, apparently convinces an admiral running a carrier group that he can be vital to the cause. Yet he's also leaving and going to refugee sites during the crisis; even allowed to attempt to flow back home to San Francisco from Hawaii before the MUTO attacks (in other words, before the crisis ends). He's then allowed to come back and retro-fit a nuke; etc.
Decisions by the wife- ok, a giant monster is coming towards San Francisco bay area via the ocean, and she has her son at her hospital (probably one of the safest locations around at that point). Let's put our kid on a bus and let him ride across the Golden Gate bridge; sure, that's bright.
Godzilla causes a tsunami leaving the ocean in Hawaii (we get serious footage of this), and barely a ripple diving back into the ocean in San Francisco. He at some points causes destroyers to almost capsize with his swell, yet swims directly under the carrier without any turbulence.
Speaking of which, do you really keep your carrier group positioned within a couple hundred meters of Godzilla while he's crossing the Pacific, surrounding him on every side? Seems a little risky, as even an inadvertent kick or tail-splash would create a lot of damage, let alone actual aggressive action by the big beastie.
You get the point. It wasn't fun/action-packed enough to match the superhero/transformer action movies; it tried to take itself too seriously to be campy, and yet there were way too serious plot holes to be serious.
On the plus side, the actual Godzilla CGI was good. He looked cool. He just needed a better movie.
