“Saint Maud” (*1/2 out of four) was a sputtering horror psychodrama about a dedicated nurse (Morfydd Clark) who becomes dangerously obsessed with saving the life and soul of her dying patient (Jennifer Ehle) but this takes her to Hell and back as she is forced to confront the demons of loneliness and psychosis that are creeping into her life. Many praised this horror film but I’m not among them; it’s sluggish and dour for most of its running time and ends abruptly just when it seems to be building. Clark’s sincere performance is film’s main asset. Yet another pallid imitation of “The Shining” which is another shining example of why that film was so great in the first place.
