This is a great movie that usually gets confused as a zombie movie when really it is about a virus that spreads England rapidly due to a monkey bite in a laboratory. Unlike other movies of similar genres, this is one that you can actually consider possible with all the constant threats of germ warfare and side effects caused by the drugs we make and the experiments we conduct. If you are into movies of suspense, some gore with a great plot, then this is the movie for you. Made with digital camcorders it is the first of it's kind and this type of filming can be witnessed in the scenes with the infected. They move abnormally fast. That is due to the pictures taken with the cameras which is much different from a typical film reel. It has more of a start stop animation quality. This is a must see and if, and when, you like it you will need to watch 28 Weeks Later. The sequal that picks up where it left off. Watch both movies if this is a genre of liking for you.
