Since the movie is based on a book by Max Brooks, I do not know to what extent could we blame the plot's holes on the director Marc Forster. For those wanting a blend between "Resident Evil" and "The Day After Tomorrow", this is your movie. But be forewarned of the glaring plot holes.
Second, the Israeli wall scene seems a bit off. In the Israeli wall zombie attack scene is shown heaps of zombies making a mountain of themselves in order to climb the wall. Then, Gerry's conclusion was that the zombies were attracted by the noise of people singing. C'mon. Even if those Jerusalemites were only whispering, half a million people standing close to a wall would surely attract zombies.
Third, is the fact that the aeroplane crash seem to occur conveniently close to the UN health facility in Cardiff. Also, the only two survivors of the crash was...who else? Gerry and Segen, the Israeli soldier he has picked up at Israel (played by Daniella Kertesz). It is not shown how long Brad Pitt walked from the site of the crash to the health facility building, but judging from the fact that they didn't have to spend a night on the road, they probably walked there three or four hours, at most. The coincidence is a bit stretched thin here.
Fourth, is the fact that it is Gerry who found the vaccine! Infect yourself with a deadly pathogen, everyone...and you'll be saved! There are at least five other actual scientific researches in that health facility building, and it never occurred to them to try out a vaccine like that.
For an overtly-hyped zombie thriller drama, I must say that "World War Z" is rather disappointing. Yes, it has exciting trailer. Yes, it has fast-moving zombie attack scenes. The CGI is excellent too.
However, such great-looking features are unfortunately accompanied by weak story line.
