I haven't read the book... mostly because I'm sick to death of zombies and would prefer skeletons or dinosaurs in my apocalypse.
Gimme World War Skelesaurus and I'll be interested.
My only exposure to the book is my friend, who thinks it's highly overrated. Then again, he says Doctor Who is overrated, and I'm literally the only person whose ever seen eye to eye with him on that topic. But he did explain enough of the premise for me to understand just how off the mark this movie looks.
Ignoring that and looking at it as just a movie... eh... I guess it doesn't look terrible. Too CGI heavy, always looks too smooth to be real. The real problem is I just can't get into it :/ the whole premise is a smack in the face I can't help but flinch at, so I can't suspend my disbelief. I see zombies, walking corpses, fighting what looks like a fully geared up and organized military... I don't care what body count they put up on the screen or explanations like "Oh it happened so fast" that just does not compute o.O You can't show a few seconds of jets and choppers carpet bombing zombies with ease and then clip to OMG WHAT DO WE DO WE'RE DOOMED ALL WE HAVE IS CRUISE MISSILES
