I didn't watch because I found the concept disturbing. It's one thing to make a programme 20 years later. But seriously, this is a person who spent the first half of her childhood abused and neglected, then became so high profile that she had an identity change. An identity change?! Imagine you had to pretend you weren't who you'd always been? That's awful, and to an INNOCENT child.
Then she spends the next half of her childhood essentially in hiding. And then just as she becomes a legal adult, setting sail into the world in her own right, someone decides to make entertainment about her trauma, deleting HER.
And it IS entertainment, or the BBC wouldn't have shown it. This wasn't made to show psychology masters students, this was on national TV at prime time.
And while other people get nights out, weekends away, stereos or whatever big gift to mark their adulthood, this person who has been through more than most of us would want to imagine gets HER trauma, the incident that deleted her previous existence put in national TV and told it's about "community spirit".
Maybe in another 10 years it would have still been difficult, but she'd at least have had a chance to be a adult first.
Watching/looking at child sexual abuse images ("child porn") is a crime in part because it perpetuates the crime for the victim long after it's taken place. I see this documentary, or whatever it's being called, as doing exactly that.
