Because it's funny. The first time I read title I thought it was a movie about a bank robbery with car chases and more action but I never think it could be a comedy-horror where the action takes place in northern UK. A policewoman (Lisa) is sent to replace a colleague went on vacation for two weeks. Arrived in town she meets her fellow O'Shea witch is rude because he doesn't have the good sense to help her with luggage. He is an alcoholic and it is ironic how he manages to stay in police business with this flaw. A meteor falls near the island and they find themselves invaded by a strange creature that resembles an octopus and needs blood and water to survive. Immediately, the monster make some victims, some fishermen, a few whales occur at the edge of the sea for no reason and people begin to worry when one of them capture a baby octopus and keeps it in a aquarium. It begins to attack one by one and the two police must team up to save the others. Know then that the combination of blood and alcohol harms octopus and so they organize a party at the village pub where they hope to save them all by make them drunk. Someone try to find out what is really going on but too late and the monster comes already after them. Are discharged one floor above and Lisa is sent to bring back the car keys to create an evacuation plan to destroy the octopus. I liked that at first Lisa seemed very serious she is not smiling, had no sense of humor and after they drunk her turned into a completely different person. Who knows maybe eventually alcohol can save your life ... but of course only in the movies.
