To put such an original and unusual feel on a genre such as the ghost movie is a prowess in itself. For better or worse. I love the atmosphere created here. Ciaran Hinds gives a subtle yet moving performance under a good direction and a haunting music.
New genre: Horror/Romance. The mood is an odd mix of languid and playful and feels nothing like conventional horror. And then some of the most chilling and visceral scares ever happen. The cinematography is gorgeous. The ending is poignant. As others have said, this is a truly unusual film.
