Wow! Is all I have to say about this episode and that is not a good "wow" but I disappointed one. When I heard the plot of the episode is one sex trying to kill of the other one, I thought it could be pretty amusing. And it was a good idea, the only good idea. It's like they put a lot of thought into the main plot and just couldn't find a way to execute it right so they took off their thinking caps and decided to just make it about a virus that aliens inflicted upon us. I kid you not.
Its just the perfect example of a d-rate low budget science fiction episode. And when you start watching it don't expect anything more than that because if you do you will be sadly mistaken.
