Six years ago, a probe carrying samples of alien life crashed in Central America. Soon after, horrific alien creatures (somewhat like giant insects with tentacles) began to appear, and roughly the upper half of Mexico was quarantined as the "Infected Zone," with the U.S. and Mexican armies fighting the creatures.
Andrew Kaulder (Scott McNairy) is a photographer, taking pictures of the creatures and their victims in South America, when he gets an unwanted assignment: Escort Sam Wynden (Whitney Able), his boss' daughter, back to America. At first all they have to do is get to the coast, where she'll get on a ferry that goes straight to America. But when their passports are stolen, they have to take a more expensive and dangerous trek, by car, boat, and foot, through the Infected Zone.
That said, Andrew and Sam aren't terribly compelling characters. Using the darkness to hide the monsters works fine at first, but after a while the movie feels like it's spending half the time in the gloom and obscurity of night. And there are times when the movie meanders, bringing boredom into the mix.
Monsters is an interesting movie: Not a great movie, but different and more thoughtful than other movies with aliens and, well, monsters. (And the newer dvd edition has a massive amount of behind-the-scenes extras; the second disc is devoted solely to them.)
Overall grade: B-
