This is a unique film that doesn't feel like anything I have seen before. The movie tells a very personal story. The camera almost never leaves Saul. Much of the film seems to take place in real time. We spend half of the film looking at the back of Saul's head as he moves from place to place. As Saul moves around the camp, we witness one horror after another, most of which are in the periphery, or barely offscreen. Things happen that are never explained. There is a mild sense of chaos everywhere in this story.
I find the subject matter depressing, but not the movie. The story creates a kind of suspense as Saul tries to find a way to bury his son, and as the revolt builds to fruition. The film gives us a different perspective on the Holocaust, and it is intensely personal. Many people would not be able to watch Son of Saul because the Holocaust is too horrible to contemplate, but this feels like a story worth watching.
