The best way to describe this would be Alien Lite. It’s the same basic premise, played out on the International Space Station. A probe returning from Mars has a dormant cell that soon starts to grow when they cultivate it. Sure enough, it gets bigger and bigger and someone makes a stupid mistake, letting it loose in the station. It is adaptable and very fast. It picks off the crew until only Jake Gyllenhaal and Rebecca Ferguson are left. They believe that the critter would survive a re-entry, even if the capsule burned up. I find that unlikely, but who knows? Anyway, I pretty much hated the ending. I won’t reveal it, except to say that I like thriller/adventure/horror movies to end with some hope.
