As with most zombie movies the plot is rather contrived and unbelievable (even if you accept the existence of zombies) but if you want to watch zombie movies in the first place that is something that you are supposed to be immune to.

This is another variant of zombies being created by some virus and rapidly taking over most of the planet. As I said, the entire story is somewhat unbelievable. When I first read about zombies as a kid there was always some supernatural/magic stuff involved. I think I liked that “explanation” much better than the virus nonsense which just have too many holes in it... read the rest.
