A slightly different premise to the usual "Aliens come to earth" movie. This time a NASA probe, sent out to look for signs of life, brings back live samples. Unfortunately it breaks up and crashes, over Mexico, on re-entry, an scatters the samples which survive and grow. Now the US/Mexican boarder has a whole new "Alien" problem and the area is walled off and declared a no go area.
Into this situation is placed a photo-Journalist who is told by his boss to escort his daughter home to the US from Mexico. Travel is hugely difficult and expensive. When he is robbed the only way home is through the exclusion zone.
The two leads are young and attractive and do a good job. The action is mostly at a distance with war planes flying over and explosions in the distance, but the sense of unease in the danger area is very well racked up. When action does happen it is all the more surprising.
Don't believe the DVD case when it describes this as an action movie, it's really not. Action is fleeting but there is tension and when the huge alien creatures are finally seen in all their glory it's a brilliant, engaging scene.
Monsters is a slighly strange title for the piece and you wonder who the "Monsters" really are....
