Okay, so I rented a Brad Pitt movie. How bad could a Brad Pitt zombie apocalypse movie be? Well, really really bad. World War Z is deeply awful. It's offensive on so many levels, I'm not sure where to begin.
It could be the totally predictable plot, or maybe the fact that there were few female characters and they were mostly relegated to the "helpless females/caregiver" role (a nine year old boy gets the role of protector of women and girls who have already shown themselves to be survivors). The worst, however, was the blatant pro-Israel, anti-Palestinian propaganda.
After escaping the zombie-laden US, the hero (Brad Pitt) has a conversation with a Mossad agent in Jerusalem. Said agent rationalizes the existence of the wall between Israel and Palestine. Then Palestinians, who are all zombies, flood the wall and take over Jerusalem.
This falls under the WTF am I wasting my money on category. It doesn't get any worse than that, but it doesn't get any better. 2 hours of my life I'll never get back.
