Just watched the movie and I was really disappointed. The movie focuses on three different groups of people and tell their stories through three different camcorders (one for each group). Never understood why people travel with camcorders and have them on the whole time, mostly shooting the countryside and occasional zombies attacking them in a deadly outbreak. The shaky camera style made the film hard to follow and didn't show most of the action. Moreover, the zombies attacked mostly night-time, so all I got was shouting. I felt sad for the characters who were caught and possibly eaten by the slowest moving zombies of all time. The acting was awful as well. So, avoid watching it and don't be fooled by the DVD cover.
The film however made me thinking about buying a farm in rural England. It is so peaceful, even in a zombie invasion.
