So this has done very, very well. And the second one's now officially on the table.
I really liked the book, went into this expecting a train wreck and was honestly blown away. It's relentlessly paced, Pitt's great and crucially the character's defining characteristic is he's SMART. The entire film hinges, on several occasions, on him noticing stuff and deducing what's actually going on. It's a really refreshing change and it works very well.
Is it the entire book? Hell no. It's a single story that bounces off and incorporates a few other sto create what's very clearly the first act of a trilogy. There's closure to this film, clearly, but the war isn't over by the end of it. What there is instead is a beach head, a moment's breathing room and humanity regrouping. With that in mind, I suspect the second movie will be the search for Patient Zero and the third will be the campaign to retake America, probably with Yonkers factored into the front of that one.
It's not perfect by any means, but frankly almost nothing is. I'm sure other people will gleefully rip the thing to shreds shortly but it's one of the standout big Summer movies for me. It's smart (And most of the mistakes can be chalked up to in character human error), really tense, fast paced and even builds in a gorgeous, elegant response to the fast/slow zombie issue (Their answer, without context, is 'both').
I dug the hell of it. Good movie.
