This amazing movie, with the amazing Anthony Hopkins, doesn't just tell a story about a man enduring an Alzheimers like illness. It let's you experience sliding down that slippery slope right along side him. You start to feel like you don't know what to believe throughout the film. Hopkins, as always, is top notch and Olivia Colman , who plays his long-suffering daughter, captures all the feelings of a 24 hr care-giver. You can tell she's really been through it with him. My father had Alzheimers and it really hit home with me. I may have used a box of tissues but I can honestly say this movie is the best I've seen of it's kind. It's an important film.
