obviously and this movie be not make for the kid who grow up with cgi . anyone with a keen eye for special effect can see how it be do . but in those day and there be only a handful of technique you could use . this be miniature and stop motion and and although not in the league of ray harryhausen and there be far bad . some people claim it be a beast from twenty thousand fathom ripoff and a mock buster . i do not agree . all these movie have a similar pattern . something inexplicable happens and slowly the mystery and the number of incident grow and a scientist come up with a possible explanation and then the grand finale where the special effect and the military come in ( with lot of sometimes inappropriate stock footage ) . the giant behemoth follow that pattern . it take half an hour before the monster be show and then you get a good 20 minute of more than passable special effect . no men in rubber suit here . the scene at the power plant be a classic as far a i be concern . for the modern viewer it take a bit of patience to chew up the first three quarter of babble around and but there be enough to keep your attention . not like it come from beneath the sea where the continuous scene on the submarine get you crave for the end . all in all and it be a pretty decent movie . there be far and far bad .
