For a movie called "Octopus", there's a lot going on here, and some of that even has to do with a large killer animal. There's an unusual amount of plot for a movie of this nature, so much so that the titular animal doesn't even make an impact on the proceedings for a full half hour. This film is much more concerned with a terrorist being transported back to the United States in a submarine of all things after blowing up an U.S. Embassy.
I guess it's an important plot device since it's impossible for an octopus to pick off people one by one in a submarine, no matter how clever he may be. The special effects are typically shoddy, with CGI replacing imagination once again, further signaling the downfall of movies on the whole. It's just one more buzz killer in this ridiculous, deathly dull picture. The impending meeting between the sub and the luxury cruise liner shows promise for pulling the movie out of the doldrums, but that is a let down once again. Again, it's marred by sub-standard special effects. And it's only five minutes out of an overlong film that seriously could have used some editing.
The screenwriters try to salvage it by injecting some much-needed humor into the dialogue during the last half hour, but it's too little too late. It just feels out of place in a movie that was serious to the point of absurdity for the first two-thirds. You just have to wonder why they filmmakers thought it would help at that point in the game.
For a movie like this, campy fun was the only way to go, and there's nothing fun abut "Octopus". The title creature is an afterthought at best, and he has very little screen time.
