It’s exciting to see Shyamalan on such confident footing once more, all these years later.
If perfect fools can hold driver's licenses, why can't creatures from outer space be just as dumb? And if they are bounty hunters, why shouldn't they be trigger-happy, firing at everything that moves, like a television set, for example? We always assume that visitors from other worlds will be far more intelligent than we are, but maybe they'll just turn out to have faster means of intergalactic travel.
In the opening scenes of "Critters," a spaceship is approaching a barren asteroid that has been converted into a prison. It is carrying on board several of the dreaded Krites, who are furry little bowling balls with dozens of rows of sharp teeth. The Krites escape, take over the ship and land on Earth. And bounty hunters follow them here, while the nasty little critters are terrorizing the countryside.
What this gives us is a truly ambitious ripoff of not one but four recent science-fiction movies: "Gremlins," "E.T. The Extra-Terrestrial" (1982), "The Terminator" and "Starman." We get the critters from "Gremlins," and from "Starman" we get the notion that an alien can assume the outward appearance of a human being. (That is a particularly attractive quality for an alien, especially in a low-budget picture, because then you can hire an actor and claim he is inhabited by an alien and you can save a lot of money on special effects.) From "E. T.," there is Dee Wallace Stone, who played Henry Thomas's mother in that film. Here she is the equally dubious and harried mother of young Scott Grimes, a plucky kid who goes into battle against the invaders.
The movie takes place in a small town and the surrounding countryside, where the vicious little furballs start attacking everything that moves. They have a lot of tricks at their command: They can eat you like a piranha, shoot darts at you from their foreheads, and curl up into a ball and roll away.
