On a weekend retreat in the snowy Maine woods, the quartet run into an alien incursion that begins ominously, with animals fleeing the forest but then throws in enough phenomena for a whole season of The X-Files with leftovers that could kit out a video nasty, notably toothy worm parasites memorably named "shit weasels" and a giant ET that turns to red powder and possesses Lewis. Mad militarist Morgan Freeman shows up and claustrophobic lost-in-the-woods business is diluted by a helicopter attack on a downed flying saucer and an internment camp for red-blotched infectees, while the plot boils down to something as simple as a race to prevent a worm from being dropped in a reservoir (which will end the world).

On a scene-by-scene basis, it's entertaining and creepy so long as you don't think too hard about details, like why someone charged with trapping an alien by sitting clamped on the toilet lid would risk reaching down onto a bloody floor to get a toothpick or why the aliens didn't just land by the reservoir in the first place. --Kim Newman
