Every now and then we get a great film that covers tragedy and mental illness in a very special and poetic way. The movie truly goes to some dark places and shows what family history, bullying, abuse, fear of folklore/horror tales, outcasting, etc, can do to a person with an undiagnosed mental illness/Schizophrenia. The film almost structured like a documentary and montage/flashback project. Many of the nightmare like sequences are very disturbing and make you question what is reality within the movie and what is inside the main character's head/hallucinations. What happened on the boat? What was the meaning of the two final scenes? I think it works fantastically in the two main ways the viewer can interpret it. The movie can be seen as a dark drama and even an understated horror/thriller. Wonderful performance by a young George MacKay here. Kate Dickie also turns in a heartbreaking performance the mother.
