Meh. Visually it is good, with dark images of the forests of Ireland, well-created depressive environments and acceptable performances, but the story lacks tension. Even when you doubt whether something is really happening or if everything is in the mother's mind. There is also a lack of story on the reasons that led her to go to the countryside. If the intention was to raise doubts about the mother, as there was a lack of development in the rest, it only added to this failure.
