This movie doesn't have a clear message. Instead the title "requiem" really shows what this is about: looking at a person's life in every aspect of it. So the storytelling has to be much more from a distant viewpoint. Some may call this documentary-style as it seems to show a real social case study. Personally it reminded me a little bit of the early Scorseses style of movie-making (e.g. taxi driver): neutral viewpoint, but still subtle messages within, and finally the big clash in the ending, when all strings of the story developed throughout the movie come together.
For me, this is the best way of doing such a movie. First everything feels so normal as you watch the movie. In the end extreme situations begin to develop. Because you know the context, even it is a really extreme situation, it seems to be not at all inexplicable but very real, which it actually was. I could personally feel the helplessness with this situation, because I could not blame anybody in the movie, there was not a side who did anything wrong on purpose. All are just human beings, who are presented perfectly and believable through very good acting. The final shot of the girl's face with background organ music expresses many feelings I have about the movie.
All in all it is a very good movie, but of course it still does not feel as great as some of the best movies of the time. 9 stars
