Just saw it and really enjoyed it. Liked the subtle humor of the soldiers in Korea and I also chuckled at the brainchild slipping and then offing himself.
Also, how terrible of a stalking companion was that doc in the WHO facility? Not one, not tow, not three, not four, but FIVE loud noises?!?!
My last comment is this - that really wasn't a World War Z movie. Sure it had the name and a few basic premises in common, but it really wasn't the same or really even similar to the book.
I enjoyed the book and this movie, but I do hope someone makes a miniseries from the book at some point to tell a dew of the other stories.
