I liked it enough to order Godzilla vs. Mechagodzilla II, a sort of sequel.. more monster action & more Akira Ifukube music!Can't wait.https://en.wikipedia.org/wiki/Akira_Ifukube http://www.ebay.com/itm/360578677392?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
Oh, that's the best movie of the Heisei-Era series, tons better than G vs. King Ghidorah. Although in between them (both chronologically and in quality) is Godzilla and Mothra: The Battle for Earth.
My favorite thing about Godzilla vs. King Ghidorah is the idea that radiation can turn three animals roughly the size of cats into King freakin' Ghidorah. I mean, I know it's a Godzilla movie and all, but that's quite the growth spurt. And I thought radiation was scary when it just gave people horrible diseases.
I didn't like the Heisei assumption that any prehistoric or monsterish animal exposed to radiation would uniformly turn into a giant kaiju. If that's the case, then why aren't there a bunch of giant humans running around due to radiation exposure? What I found surprising about the original movie is that it didn't say Godzilla was a mutant -- just that he was a prehistoric survivor that had lived undiscovered in the depths, like the coelacanth, and been displaced from his normal habitat by the nuclear tests -- and made radioactive by exposure to them, presumably. The idea that he was actually created/made giant by radiation, even powered by radiation, is an invention of the Heisei series, I believe.
(I believe the first movie to show giant monsters created by radiation was Them!, the giant-ant movie which came out a few months before Gojira. But it posited that it had taken years and many generations of radiation exposure for the ant population to mutate into progressively larger forms, rather than specific individual creatures growing to giant size.)
Also, apparently neither Godzilla nor King Ghidorah breathe oxygen. Or they inexplicably have gills. And King Ghidorah can survive trapped on the bottom of the ocean for hundreds of years after getting one of its heads blown off. And the Godzilla dinosaur can survive for at least 10 years, possibly 50 (the wonky time travel in this movie makes it hard to determine if the "new" Godzilla was really created in the 50s or 90s) in the same location, after being critically wounded no less.
Godzilla's always been portrayed as amphibious, able to survive indefinitely underwater -- see my above comment about the original movie's explanation for his origins. Most Godzilla movies have him appear by rising out of the ocean and leave at the end by returning to the ocean.
And it's long been a conceit of the series that Godzilla has unparalleled regenerative abilities. That was even suggested in the original film -- Professor Yamane argued that Godzilla should be studied rather than destroyed because we could gain new medical insights from studying his ability to survive and withstand radiation and so forth. Other films like Biollante and Millennium have revisited that notion. The general rule is that even when he's seemingly killed, he just hibernates/regenerates undersea for a while -- even for decades, as in The Return of Godzilla and GMK -- and then eventually comes back.
