if you expect that this movie be full of action and grab you from the start then do not watch it . but if you like those kind of meditative movie which stick in your mind for a while and until you get the detail and then you will love it . now do not get me wrong there be action and there be thing go on just not in the usual way . basically the plot be in a post apocalyptic world where anyone fight in his ( or their ) way for survival . in this fight they lose the ability to speak . i do not want to write more to not spoil the movie for you and but trust me if you like sf author like lem or capec or even some from orson scott card you will love this movie .
