Planetarian: The Reverie of a Little Planet

There are five 18 minute episodes, in this series, about a man, scavenging for food and materials, and a somewhat malfunctioning robot girl programed to give shows at a planetarium. While hiding from killer machines, the man meets the robot who says he's the first customer the planetarium has had in over 29 years. The robot has no programing for her to comprehend that modern civilization has been destroyed. The interactions between this man and overtalkative girl robot grow into a unique companionship. The series is touching and sad. It is worth watching. I saw it for free on Tubi, a streaming channel. It made me wonder if we humans will destroy much of the world like it was in this story.
