Watchable enough. Didn't like the design of the alien but liked its behavior. Should've had a less forgettable title.
A lonely disfigured man with a passion for trainspotting & numismatics has only one friend in the world: his loyal dog, who happens to have a severe food allergy which causes his skin to become painful & red. Finally the man discovers the one food that his dog is not allergic to, which happens to be human flesh. The film tells the story of his trials & tribulations as he struggles to save his best friend's life.
