This is the ALIEN scenario, of course, though it's a really good one. It's shortly in the future. A crew on the international space station eagerly awaits a probe returning from Mars. It's carrying the first soil samples ever. Almost immediately they determine that there is a single-cell organism in it-and with a bit of electricity and glucose it awakens and quickly begins to reproduce. The biologist is infatuated with it-until it grows large enough to crush his hand. By this time it looks like a cross between an orchid and an octopus. The creature escapes the confines of the lab-and views the crew as a food source. It increases in size with each feeding. One by one by crew bites the dust, which sucks because there's enough characterization established that you like these astronauts, from Ryan Reynold's Rory Adams to Rebecca Ferguson's Miranda North to Jake Gyllenhaal's David Jordan. And while I could see where the climax/ending was heading I was still entertained because it was done in a cool way. Highly recommended.
