Monster movies run from really good to just bad and this one, out of Korea, is very good.
It's about a giant squidlike monster, which is the product of toxic chemical dumping. The squid monster soon takes the daughter of a snack bar owner, Hie-Bong (Hie-Bong Byeon). He doesn't take this lightly and tracks down the monster.
This is one of the best monster movies ever made. It's full of all the things that made the 1950's monster films fun and exciting to watch. It also works well as a satire.
I can't really find flaws with it's very well rounded.
