Very decent paint-by-numbers monster/nature-run-amok movie, for a paint-by-numbers monster/nature-run-amok movie. New veterinarian comes to a small town where all the farmers have an arrangement to buy futuristic new feed from a big sciencey company, which it turns out causes ordinary microscopic parasites to turn into giant, bloodthirsty monsters that destroy people and animals from the inside.
It’s got big rubbery monsters chasing women in their bra and panties, it’s got tough-as-nails farmers shooting shotguns at big rubbery monsters, it’s got rubbery chest-bursters bursting out of people’s torsos, it’s got an innocent, wide-eyed tow-headed boy for pathos who (awesomely) gets eaten by a big rubbery monster. What do you want from a monster movie? It’s not “Citizen Kane”.
I liked it, I was totally entertained.
