I never for a second expected much similarity to the book. So there's that. And, to be honest, given that the book takes place 10 years after the outbreak having it take place during it's inception makes a lot more sense. Also we're so used to zombie stories that take place within small groups of regular people, it's fun to see a globe trotting zombie adventure and a different side of that tale. Everyone's going to have their opinion on the zombies, but I thought they worked well for what they were going for. The chattering teeth one was wonderfully creepy. There's some really fun, smart, inventive things going on here on both sides of it. A zombie action adventure film with a big old heart. I liked it.
