Now I hate to admit this, but as a huge Zombie Survival Guide fan, I went out and bought World War Z immediately after it came out. Unfortunately, for some reason I have never actually cracked it open. I'm not sure why, and I really have no excuse. Either way, this film apparently just has absolutely nothing to do with the book anyway.
I'll start with what I like about the movie. It is pretty intense. It has a PG-13 rating, which I will talk about later, but still seemed violent and intense. The action scenes definitely kept my attention, and the zombies seem to be a genuine threat. All of the scenes with zombies chasing people had me on the edge of my seat. Parts of the film felt like Left 4 Dead the movie.
