It's a fantastic sequence and the cuts are done so well as to be virtually unnoticeable unless pointed out.Emmanuel Lubezki. Went on to do Gravity, Birdman and The Revenant. The other oner in Children of Men is epic.
EDIT: I just watched that with headphones on. The sound is absolutely incredible too. I also love the fact the blood spatter on the lens halfway through wasn't intentional. They finished the shot and the camera man was saying it was all no good, when they watched it back they realised it was absolutely perfeect.
True Detective has a comparable oner scene in season 1 - utterly brilliant television.
