It is quite some time until we get to Yongary though, the first part of the film can drag a bit and includes a couple of newly weds menaced by Icho (Kwan Ho Lee), an annoying child, who borrows secret technology from the lab which has a conspicuous lack of security. For some vague reason the wedding night is ruined by the groom being ordered into space. While he is up in orbit radio contact is lost and the earthquakes begin. Finally, Yongary emerges from the Earth. Yongary is largely immune to conventional firepower, though doesn't like a certain chemical...
The film is great fun once Yongary makes his appearance and we get the usual scenes of destruction, terrible looking tank and helicopter models, and people running in terror. The film doesn't make a great deal of sense (for example the scientist Illo (Oh Yeong-il) taking his girlfriend (Nam Jeong-im) along with him on a helicopter flying above the fire breathing monster as if its some kind of day trip!) however is a decent entry in the genre.
