Wasn't sure the first few minutes, then became very emotionally involved with the lead character and remained at the edge of my seat. Toward the end I was crying along with her. I even developed an opinion of what her illness might have been. The idea of appearing to be a documentary really worked nicely. The filming style reminded me of Lars von Trier's "Breaking the Waves" or "Melancholia". Loved the open ending which continued to make me think about it after the closing credits. Will definitely be seeking out more films by this director and lead actress. May rewatch the film "You Can Live Forever" which she also was in.
