Yes, Life borrows from many movies that have come before. Gravity, Alien, The Thing, and a dozen other titles. But it's good at what it's doing.
Six people aboard the space station have received some samples from Mars, and within them, they find a dormant organism. It is the first proof of life beyond Earth. Nicknamed "Calvin", the organism grows from microscopic to about the size of a flower until it goes dormant. During this time, we get the wonder of discovery and get to know the people on board.
Once Calvin starts killing people, the movie kicks into high gear. Calvin only gets scarier as he gets bigger, and he feels like a very smart animal determined to kill off anything that would threaten him. It. This sinister plantlike octopus spider thing floating in zero G with everyone else.
It's not as majestic as Gravity or as scary as Alien or as thoughtful as Arrival BUT!... for what it is, it delivers on the thrills and the special effects. I wish it had been more successful at the box office. I would have watched a sequel.
