Going into this movie I had completely shut off the fact that it wasn't going to be anything like the book. Upon seeing it and with The Last of Us still on my mind, I just couldn't help but laugh at this movie. There were so many scenes that just made me angry in this because of the stupidity of what was going on by people and what the actors were saying. I guess you could say that the writer was just not that good, but the delivery that the actors used them in was beyond stupid.
World War Z is obviously a very Hollywood movie that uses cheap horror tricks to try and make it seem scary. It was hard watching this though because of how well The Last of Us and even to a certain point The Walking Dead, the TV series, game, and comic, depict a world destroyed by a global infection. What was different thought is that these series decided to take a step back on Zombie media by showing what the human condition would be like under an apocalypse. They had more to do with what George Romero was trying to show in his films by focusing on a group of people who are trying to survive in a very hostile world and where the zombies are more like obstacles.
I guess if you need a movie to go to turn your brain off and just enjoy what's happening on screen I could recommend this, but even then lovers of zombies and of the book will more than likely cringe during certain scenes in disgust.
