It had to happen! A new TV series based on the zombie premise, called The Walking Dead. Starts off with a guy coming out of a coma in hospital (cough: 28 Days Later). This chap is a US Sheriff who was wounded and he sets off across the USA to find his missing daughter and wife, killing the undead along the way.
Explanation for zombies? Virus. Jeez, I catch a Virus, I normally end up in bed for 24 hours unable to move, rather than becoming an undead cannibal. But hey-ho.
