What can I say? Can you have any expectations from a movie about zombies? Whatever, not even a popcorn flick, maybe a snickers and diet coke flick, that's about it.
Is this going to turn into a straight to DVD then ultimately Sci-Fi channel series like Species?
Besides Milla Jovovich being in it, don't look for too much else.
However, there are some good books on the Genre, Max Brooks' World War Z was excellent.
