Well it literally is a different animal from Ishirō Honda's seminal 1954 movie about the giant atomic lizard who wakes up in a bad mood. Here the American version clips the atmosphere considerably (and the running time), craftily edits Raymond Burr into Honda's movie and of course removes the anti-American sentiment that once existed. Yet the film did prove to be very popular with English speaking film fans and further enhanced the growing appeal of all things Godzilla like.
As it is it's a decent enough film, especially if you have never seen Honda's original. For sure it's still creaky in that "man in rubber suit" way, but the iconic creature is still thrilling as it goes about its merry way destroying some carefully constructed model workings. The nuclear war heedings are still there and there's much fun to be had, intentional or otherwise. Its pale in comparison to the original, but it's not a stinker either. 6/10
