For monster lovers, this has to rank up there as one of Toho Studio's greatest and most satisfying giant monster movies. For those looking for it, there's plenty of nonstop monster mayhem and devastation on tap. However, it's hard for me to decide which of the two versions I prefer; the Japanese original (which calls our creatures "Frankenstein's" and is a direct sequel to Toho's own FRANKENSTEIN VS BARUGON, aka FRANKENSTEIN CONQUERS THE WORLD) or the U.S. edition (which christens the beasts "Garganutas" and works better as a separate stand alone story). This may be a rare occasion where the American rendition proves to be more entertaining, for a few reasons...
One grisly sequence shows the evil monster chewing a woman victim up like a piece of meat and spitting something out; in the Japanese version it's a bouquet of flowers, while in America it works more effectively as the girl's clothes.
Another quality I prefer in the U.S. edition is some of the music. Just works better for me during the action sequences of the monsters being fought off by the army as well as when they're beating each other up.
In the American film, Russ Tamblyn is especially funny to hear while looping his own embarrassed voice into English. And no matter which version you settle on, you'll still get the treat of hearing a female nightclub singer belting out that horrendous and long-vilified classic tune with hilarious lyrics that include "the words get stuck in my throat"! Worth watching for this alone! *** out of ****
