Considering the era when this picture was made, the special effects are actually quite good. The story line follows a
specific pattern at a medium pace that is easy to follow.
The only annoying part of the film is each time the ships big guns blast away, there is someone yelling the word "Fire" into
a phone. But, in spite of that minor error I would still say the actual suspense and "edge of your seat" feeling is captured very well. This movie is a "keeper."
