When the film was first announced, people really wondered how the book could ever be transposed to a summer blockbuster. I never read the book, so I can't really comment about that. But overall, it seems that there may have been something lost in the transition from paper to screen. While it's not a bad film by any means, it just seems that the production lost focus and couldn't deliver an original or fulfilling conclusion. An hour and a half of build up leads to a scenario ripped right from I Am Legend. Many other similarities could be noted between the two films, but the ending was just a sad reminder of a much better movie starring Will Smith.
World War Z should have been allocated to a fall release when it wouldn't have to battle such heavy hitters like the Man of Steel. Zombie enthusiasts will find a lot to like about this movie, but might end up a little reluctant to add it to their list of favorite genre entries. The movie is a just above average effort that could have been a lot better had more time been focused on rounding out the final moments with something more effective than a montage and a standard monologue explaining what just happened.
Comparisons will be made to several other films including 28 Days Later or I Am Legend. Just know one thing: Both of those had something better and unique to offer.
