This is a typical b movie the acting is bad special effects are non excistant and to top it all off the movie doesnt stick to the original story. In the original the element Berinium was found on the planet 20 years before the movie takes place then jump to the second movie and suddenly its 85 years prior yet the commander escaped the planet 13 years prior. So that makes it 33 years before the element was found on the planet and 13 years after the original movie. If you make a second movie then please learn how to count.
