This movie was about some astronauts who find a single cell organism in a soil sample from Mars. This cell then replicates into an alien and wreaks havoc. While the movie did have a number of scientifically questionable scenes (Perhaps it was written by a Republican? They tend to ignore science.), I do not have any problem suspending my disbelief in the name of entertainment. And it had one of the coolest alien-killing-a-person scenes since Alien.
My rating: 3.5/5
