This is a very entertaining film, well-made, and has a good cast including amongst others, Dee Wallace Stone and Billy Zane.
We start off in space and the 'Krites' have just escaped from their maximum security prison. They steal a space ship and crash land on Earth. Poor Bastards!
The Krites look like a cross between a Porcupine and a Hedgehog, only with big teeth, and an appetite to match. They will eat anything, even humans. And so the fun begins.
The action takes place in a small American town, and mostly on a farm a good stretch away from the main town.
This is a very funny film, and maybe a little scary to youngsters, but they shouldn't be watching this anyway.
I highly recommend this film and it's sequel, which is even better.
