Dead Meat (2004)

Helena and her boyfriend Martin are driving through the Irish countryside when they hit a pedestrian. Unfortunately the man turns out to be a zombie infected by cows with mad cow disease and he bites Martin. Helena tries to get help from a nearby farmhouse and is attacked by zombies, including the now dead Martin.

Helena proves to be adept at stabbing zombies and after escaping meets up with Desmond, the local gravedigger. They head off on foot toward his house two miles down the road. Later they meet some neighbors who have a car. Upon hearing a news broadcast, they head toward a castle mentioned as a meeting place for survivors to be picked up by the military.

The first part of the film where Desmond and Helena make their way on foot across the countryside was the most enjoyable. They did a good job building tension. After they teamed up with the others and got in the car, the tension dissipated - although the thought of walking through a field of sleeping zombies in the dark brought back some tension.
