Dissapointed

Your post just proves you've never gone through anything traumatic in your life, so congratulations on that. First, it's filmed the way it's filmed for a specific purpose-we are to be with Saul the entire movie, and see what he sees. We as viewers are supposed to be Saul. It's a narrow viewpoint-hence, the blurriness. We see what Saul sees and hear what he does, nothing else. In a place where you have absolutely no control, where you could die any second for any reason, literally face to face with death and destruction of your own every single day, I don't think it is unlikely for someone to have wanted to control what little they could, and Saul felt that he could give this boy a proper burial and he was going to risk everything to do it. There are stories of those who committed suicide in the camps for the same reason-because they could at least control their own death and not die at the hands of the Nazis. We don't know Saul's history or even if he had/has a son, but we do know that Saul is a compassionate human being, even in the midst of the merciless inhumanity that were the concentration camps.

Another person who I can only label as "close minded and fataly stupid"

Well, good is in the eye of the beholder. I think the Fateless film you mentioned is Sorstalanság, also a Hungarian movie. I didn't like its Nobel winning book that much, but the only thing I can remember from that film is that the children acted very poorly. I very much prefer Saul.
