This was one of the best, most powerful, documentaries I've seen in a long time. At first I was totally intrigued by the fantastical, almost soap opera-like, elements of the story; the identical twins, one of whom suffers amnesia after an accident, the strange aristocratic parents, the creepy mansion full of dark secrets, but I wasn't quite prepared for the emotional gut punch that came with them as the story unravels. It's heart breaking stuff. Highly recommended. (NETFLIX) One reviewer said it's probably best to go into it knowing as little as possible, and I tend to agree. But here's the trailer anyway.
