This movie is, first and foremost, a rip-off of Alien. Pretty easy to see that right off. The budget is terrible, the acting is terrible, the writing is terrible, the direction is terrible and the music is terrible. This movie is terrible. Not just a little terrible but unbelievably terrible, in the stratosphere terrible. And thats why its so fascinating. Scene after scene, I was absolutely fascinated that a movie could be so terrible and yet it seemed to top itself. Just when I thought it couldnt get any worse, it did. I was entranced by this fact. I could not stop watching it for that reason. I watched Alien on DVD recently and I couldnt help but think of Horror Planet. Alien is so amazingly competent in every way that it is insulting to have to make any comparisons between the two. My advice is to rent Horror Planet and watch it. Watch every scene. Its not a long movie and never really boring, again not for the right reasons. Then, preferably on DVD or VHS widescreen, watch Alien. You will come away feeling such gratitude to Ridley Scott, the actors and producers of Alien that its worth the trouble of watching Horror Planet. Then, never ever ever EVER watch Horror Planet again, but keep re-discovering Alien. It is one of the greatest movies ever made.
