I get the whole dementia metaphor especially because it's prevalent in women but i really think they were onto something but it never eventuated, take nothing away from the acting because it was first class but the climax and resolution really let this movie down but more so the climax, an appearance of the old man and smashing of the windows to rid the house of him or something along those lines would've made it a true horror story, so close but yet so far and I have the bias of being an Australian behind me, what a shame, well done to the cast but ending wise average at best.
