I have to disagree with rick_7 who says, "too much unrelated footage of other family members, too much of the director talking about her feelings."
The film begins by pointedly saying it is largely about family values across generations, and this is used as a "cover" for omerta -- but it is more self-deception than keeping secrets from others.
How could Liss NOT talk about her feelings? She is not an official investigator, she is a family member at the moment all children reach when they confront the adult lives from which they descend and cease childhood, but her discovery is terrifying, goes far beyond family, reaches no finality of truth because the stories are told by people whose interest is not truth and by others, in the country of her aunt's exile, who are certain they possess truth and righteousness, but all second-hand.
Worst of all, one young person is seeking to know who was responsible for cruelty that was wrong on its face, but she finds herself in a hysterical crowd, a mob, of other young people who want the tragedy replayed.
