The topic of the movie is really dark and the whole movie portrays it.<br /> I loved how the story was developing, almost nothing is explained why the main character is like he is. To paint the better picture you need to capture from very short lines of dialogue or vague memory shots. Really good work of director and the actor for moving the whole story.<br /> I loved how few scenes were shot and how cuts in the action were made: One shot of how the main character walks into the house, cut to some house shot, cut again, this time to security guy sitting on the chair, another cut to the main character walking inside, cut to empty shot of stairs to second floor, another cut to the main character walking away from dead guy near the chair he was sitting, cut to empty kitchen, and so on... just amazing. Build of suspense in this kinda scenes is just great.<br /> Great to see once, but because of depressive and gruesome nature of the story, not much value for rewatching.
