Have you ever seen a zombie movie before? If so, then you've probably already seen World War Z. But even though you've probably seen this movie ten times before, something tells me that won't be a problem for the audiences of today because they'll get precisely what they expect....and little else. That's not to say there aren't some decent thrills or real moments of tension, there absolutely are...however, there's pretty much little to no originality to be found here. Mankind contracts a mysterious disease, mankind turns into zombies, zombies attack. Repeat. But what sets this apart from all the other times this has been done before? Not a ton. I won't lie though, I can't say I wasn't entertained by the majority of the film even if the characters were completely two dimensional. I do believe World War Z is fun, just ultimately forgettable.
The wife is given nothing to do, but stay on a Navy ship until Brad returns, but THANKFULLY that means her two stupid kids were also relegated to be there as well. Had they been in the movie as much as they were in the first half hour I probably would have lost it... they're up there with some of the most annoying movie kids I can think of. [/end SPOILER]
To be honest though, it was hard to really relate or root for any character in this film. The action starts almost right from the get go and we have no time to establish who these characters are and why we care if they live or die. Unless a screenwriter plans for some really nice moments along the way that help us get to know a character after calamity strikes (like for example in The Impossible, a film with a brief setup as well) it's really hard to care about someone in such an expendable movie when we have no idea who they are.
