This adaptation of the Dean Koontz novel, the script also written by Koontz, starts off great. A young doctor, Jennifer Pailey (Joanna Going) brings her sister Lisa (Rose McGowan) to live with her in a small, mountain town. But when they get there they find the dead housekeeper and the rest of the town completely deserted. Freaked out, they go to the sheriff's station and find a dead deputy. Where did all the people go?
The soon meet up with the sheriff Bryce Hammond (a too young looking Ben Affleck) and his two deputies, who are just as puzzled. They do find a clue however. In one of the houses there's a message scrawled and a name, "Timothy Flyte". The sheriff radios this in for more info and it turns out there's a Dr. by this name (Peter O'Toole) and he knows something. The government flies him in, along with some soldiers, but the soldiers are all attacked by this weird, entity that can change shape, so in the end there's only the four characters left.
There are some really good special effects, particularly the scene in which a giant moth eats off a guy's (Liev Schrieber of WOLVERINE) face, but it's not quite enough to make the movie all that interesting. The ending has way too much exposition, not to mention supposition by the characters, and lacks any real climax. We eventually do see this big, giant creature, yet the way we find out it's defeated is when it takes the form of a small boy and the Sheriff defeats him.
If you're a fan of the book there's really no reason to see this adaptation. The book is great.
