World War Z Review

Where do I start?  This movie had so many unanswered questions it's ridiculous.  First off, the end made no sense. How do you mass produce a vaccine when most of the world is shut down?  Also, why was no one watching the wall in Jerusalem?  It was visually entertaining but really lacked in plot.  It's not a movie I would recommend, but if you have nothing else to watch and just want to laugh at the absurdity this movie is a good suggestion.
