Not bad, not brilliant.
This isn't quite another zombie movie, 28 days was much better. This one seems to have suffered from the Hollywood touch. Yes it is fast paced with a lot of thrills, action and some good scenes, Jerusalem is on such example of a good location.
The end result was never really in doubt, Brad manages to find a way to stop the zombie apocalypse. If you are stuck inside due to the rain and have some free time this will do. There are however many other films I would watch before this one, 28 days for example.
The story line involves Garry (Brad Pitt) a United Nations investigator, he is called back into action when a mysterious virus appears. Can he find the source, the first victim and a way to combat it? Or are we all going to become victim to this new plague?
