This film starts innocently (and familiarly) enough: a group of scientists has traveled to the far reaches of space to find signs of intelligent life. This time, they succeed. They find a tiny life-form, which they affectionately name Calvin. But, um, here's the thing: Calvin is a ruthless monster that can crush human bones in a snap and grows larger with every passing second. And, well, I don't want to go too far into what happens, but let's just say the results are gory and grim.
The reason Life is so good is because it's gripping. The scenes are ripe with tension and pulse-pounding terror. Calvin is violent and ruthless. The gore is pretty gratuitous, but you want to watch it in that can't-look-away-from-a-train-wreck sort of way. I was clutching my armrest for most of the film because of the stress. And sure, maybe you can see the ending coming, but it's still a pretty wild conclusion to an already wild film.
