Made to cash in on the success of Godzilla, Gorgo is a bit of Godzilla, a bit of King Kong, and an original wrinkle or two. It's pretty good for one of these monster movies, but that's not necessarily saying much. There are some impressive (for the time) shots of London getting sacked, but the most common flaw of monster movies remains: the human characters are not the least bit interesting in their own rights.
