We've known for the past year that World War Z would be an adaptation in name only. In spite of that I'm still excited for it because it looks like a zombie movie on a truly epic scale, which I love, and that Brad Pitt has been doing pretty much only quality movies since 2006. The guy has just developed a great eye for scripts. This storyline may seem a bit trite--One man versus the apolcalypse...for his family!--but this looks pretty exciting. I can understand the decision to switch over to fast-moving zombies. I think that Max Brooks did a great job making his slow-movers work by explaining why an organized military response to them failed, but that's much more difficult to accomplish in a visual medium, so switching to fast-movers just makes sense to up the scare level of the zombies. Plus, using slow-movers is a great way to get compared to George Romero, and such comparisons rarely leave a movie looking good. Even good zombie movies look weak compared to Night of the Living Dead. While I would love to see a faithful adaptation of World War Z someday because I truly believe it to be one of the best pieces of zombie literature ever made and a great example of how to do the apocalypse right, I refuse to let my love for it taint my excitement for what looks like a pretty exciting movie, and it's not like you can't see a few touchstones in the trailer. I imagine the bus flipping as zombies swarm is the Battle of Yonkers, and it wouldn't be surprising if the assignment Pitt's character is asked to take is heading up the Alpha Teams. I'm pretty psyched for it.
