Let’s call this what it is, a startling piece of cinema from writer and director Rose Glass, a name so good it feels made up. Quips aside she is definitely someone I will be looking out for in the future. Morfydd Clark is Maud, a palliative care nurse with the piety of a saint, caring for the terminal ill Amanda, played unflinchingly by Jennifer Ehle. It’s a film of mood and presence and impending doom. Expertly building tension, stretching Maud’s fragile state of mind, until it vibrates like the thickest string of a bass guitar. To tell you more is to give away a truly creepy third act, that knows enough not to over strum that string, and let that note play. A great piece of British cinema that uses our dourness to dramatic effect. Gives me chills thinking about it.
