Much has been made of 28 Days Later… .The tag of " scariest movie of all time" and it's supposed re-emergence of the zombie genre made many a horror buff stand up and take notice. Yet 28 Days Later… is not all that.

The movie begins with animal activists breaking into a lab where a man made virus named "rage" is being tested on a bunch of monkeys. Deciding that the only course of action is to release the animals, the monkeys in turn infect all of the UK in just 28 days transforming the majority of the population into hyper, murderous zombies.

Jim (Cillian Murphy), a bicycle courier who lives in London, wakes up from a coma to find himself in what seems to be a deserted city, only to find that he is not alone as he joins a group of survivors as they try to escape those whose only goal is to kill the un-infected.

There are some things in 28 Days… that work really well. First and foremost is when the viewer is introduced to Jim as he walks through the empty streets of London. We share Jim's confusion and astonishment, oblivious to what has happened and where everyone has gone.

Second, is the discovery he makes while searching for answers; zombies. Well, not exactly in the traditional sense but close enough. Gone is the slow paced shuffle of past, now replaced with a ferocious intensity and speed, driven by the need to kill and destroy.

When Jim meets other survivors the film starts to turn into more of a story of the human condition, and less the zombie filled blood bath it could have been. Special mention to the unfortunate turn of bringing the military in the picture, turning what was a unique horror movie into a clichéd action flick.

A very frustrating watch as this could have been a great film and the first half is just that. It is a shame about the rest.
