Okay, my last couple posts on this series basically work for this one.
One original comment: this entry has what might be considered a major plot twist. It turns out in this one that two of the subject end up making friends because of their involvement in the series. One, who has been homeless for many years and seems to be mentally ill, is helped out by another, and given a place to live while he gets back on his feet. I've considered this film series a noble use of the medium, and I suppose that is debatable. But at the very least, it has had a very literal positive impact on the life of at least one subject, where he maybe would not have been able to find this kind of help otherwise. That's pretty awesome.
