Yawn! There's almost nothing to say about his film except that it's really bad. Imagine if the makers of "Manos" The Hands of Fate remade Creature of the Black Lagoon and you have this movie in a nutshell, only this movie might be even more boring.
Most of the time they film this thing through a filter during the day for night scenes....resulting in many scenes where you can't tell what's going on, and couldn't care less. The monster, Octaman, is very stupid looking, and you can see the strings on his tentacles. There are also lots of scenes of people sitting around...and walking...and driving...and absolutely nothing happening except moments of your life that you can never get back ticking away.
