This one is a bit of a slow burn. The action drags along and then hits you full force. Character building of all main characters is key treating the watcher much like the police officer in finding the clues. The watcher can as well place themselves in the role of the main character able to sympathize with his situation in living in terrible circumstances as well as having other aspects of one's life worse for wear. Watching the main character's mental state deteriorate is both interesting and saddening given all he's endured and the ending was one I was not seeing. In terms of viewpoint from the antagonist, the camera work does well in occasionally showing his viewpoint and having the audience act as the stalker which is interesting. Not a drama that has a happy ending per se, more like bittersweet and one that gets you thinking over it for days.
