After the crushing disappointment that was Pacific Rim, it was up to Brad Pitt's World War Z to try and salvage the evening at the multiplex. For the most part it succeeds because it's pretty smart until it gets dumb in the third act.
I haven't read the source book which I understand is constructed as an oral history documenting a global zombie plague. Since that doesn't make for many cinematic thrills, they've turned it into a pandemic tale/chase flick in which Pitt, a retired UN guy, is forced to trot the globe searching for the source of the zombie epidemic. He goes to Korea, then to Israel, finally ending up in Wales having close calls and adventure every step of the way.
When World War Z is being smart, it's very smart - showing us how fast bitten victims turn into monsters themselves and taping thick magazines over his forearms and calves to ward off bites. But as things progress, dumb things happen that get people killed until it seems that stupidity is the zombies best ally. When they finally get to Wales, it really starts having a case of the "Yeah, right"s until at one point Pitt is literally being the dumb girl in a horror movie setting down his weapon for no reason other than the story demands he be disarmed.
The last act was famously rewritten and I sorta hope the Blu-ray includes the massive amount of stuff they shot before realizing they were barking up the wrong tree. A common problem with movies this summer has been poor scripting and when you end up scrapping a third act, it makes one wonder if the suits at the studios really know what they're reading before sending massive productions out to shoot.
Pitt is good as always and the action is frenzied buy coherent, though generally ridiculous. It's just too bad that the zombies caught the screenplay before it was done.
Score: 6/10. Catch a matinee of you're a fan of FAST zombies; otherwise rent it.
