The real story
If you'd like to know the real story, read the book by the Dionnes: WE WERE FIVE. It's heart wrenching. They actually loved their life separated from their parents and siblings, but at age 9 that all changed. What should have been a grand reunion was actually the beginning of years of child abuse. Their mother abused them verbally and made them work like servants. They were deliberately stripped of the lovely things they brought home with them, their siblings hated them for being special and having such a lovely life, and the worst thing they report is that their father tried to molest them!
Their people skills were woeful. They had depended on each other so much, they had no idea how to interact with others. Consequently, it took them years before they had the courage to get away from their abusive parents and their jealous brothers and sisters.
I enjoyed the movie, but that was before I read their book. The book would make an explosive movie, but it will probably not be made in their lifetimes. I think there are only two left now. They live quietly, trying to shun the spotlight that they never asked for.
