in two few words. good packing :) it does not have a new story or new outstanding style. but in this movie somehow I open my eyes and watch without blinking :) maybe because it was something like quake game. like you are one of the player in the movie. it does not telling you a story. this movie taking you into the eyes of someone in the story.
it has a high tempo and I was like this "what was that" "what just happened" "what". I can give 7 out of 10.
