The movie title appears to be redundant. Clearly the Brits do not understand what to do during a major Zombie outbreak, perhaps due to the poor showing of "Zombie Diaries." A dirty bomb goes off and the film concentrates on the life and survival of Sarah (Ruth King). She passes out then comes to at a country infirmary. Here she encounters live people and zombies. They make numerous mistakes.
First, you need to secure the perimeter and eliminate the zombies inside. This is common sense stuff, but the Brits don't do it. Secondly if you are in a building that has zombies, don't ride the elevator as you don't know what is going to be outside the doors when they open. When you suspect the zombie infestation is caused by a blood borne pathogen, don't leave infected blood on your skin. Immediately wash it off and disinfect with a 10% Clorax solution. Also according to the Homeland Security handbook, the people who will actually be infected first are old people, children, and those with weak immune systems. Not every bite transmits the disease, but you need extra precaution and a holding cell/ isolation room during the incubation period. Being in an infirmary, they were in an ideal location to survive had they followed common sense guide lines.
The characters and humor didn't make it in this film like other Brit films.
