Rôjin Z

Roujien Z starts out being a wonderfully vicious satire of society's treatment of the aged. We see a young nurse taking care of an almost vegetative geriatric, one of the many old and infirm that would be in a nursing home in the USA. He is then selected to be the guinea-pig for a new, completely automated caretaking robot, a sly jab at the dehumanizing sterility of geriatric care. The story maintains its high energy and grinning cynicism until the robot goes insane and decides it is the old man's wife; from here it becomes a rather confusing action movie before pulling itself together in time for a poignant ending. Still worth watching, if you can find it.
