Gwyneth Paltrow gives a haunting portrayal of a daughter whose devotion to a mentally challenged father draws out her own mental edges. As care-giver for an elderly parent I am well aware of our fragile mental world and Paltrow's performance shines with nothing but truth. Her honesty and the emotional territory she portrayals are "proof" of her integrity as an actress. The film is impressively directed -- the script is paced compellingly and draws the viewer into a life situation that most of us simply refuse to acknowledge and try to avoid. Once the "great mind" of our genius is "gone" -- who are we? Hope Davis as Paltrow's sister does a great job of showing how striving for her "normalacy" is the ultimate lunacy. Great ensemble playing by all. I highly recommend this film.
