This came up in my documentary feed last month and at first I didn't want to watch because of the subject matter, but then I gave it a chance and it was very interesting.
The family is interesting, as it turns out the grandmother had the same pathology, which is really telling. Very, very sick family. The mom is a hot mess as well, and at first I thought her being a drug user may have been the issue with her son--but learning about her father and mother (the grandmother) tells an even more interesting tale.
Sad and disturbing but well-done film.
