basically a geneticist experiments with cows on a very rural farm. the experiment is to speed the ability for the cows to reproduce. theres mutations that create creatures that grow extremely quickly and thus need to eat/kill quickly. things go very bad from there.
predictable, not terribly scary, a bit gory though, but ultimately its a good horror movie thats worth watching.
my main beef with it (pun intended) is that this movie is more or less the same thing as "black sheep" but no where near as good. this movie is good, black sheep is great.
