Who Killed Pixote?

I saw the original film 'Pixote' and felt kicked in the stomach after it was over. Life in Brazil seems so hopeless for small children. And seeing the follow up makes it even more devastating to know that this young mans life amounted to not much. The fact that this story is true makes it that much harder to watch, translation: brilliant. The only thing was that there was no real cinematic composition, and that would have really made the film that much more moving. But, it's a great film all the same.
