This movie attracted me from the first scene till the end of the movie. The situation of this movie is similar to our real world, but something is different, so viewers think "Where is this?" at the first time they watch this movie. In addition, many mysterious elements which make viewers wonder what will happen next show up again and again in this movie. Who is this man? That city is like Moscow, but why are there no human except that man? Are they robots? Why does he kill the old man? What's in the box? A lot of questions come up viewers mind, so they cannot stop watching this movie. I think the director of this movie really understands the elements which make viewers excited and have interested of the movie.
