What story did Interstellar tell?

The core of this film is a family drama, a story about love and commitment between father and daughter. The film allows the truest and warmest feelings and waiting of human beings to naturally penetrate into such a grand and tragic human epic as space immigration. Wrapping sincere feelings in grand narrative is exactly what Nolan is good at, and its manipulation and expression are undoubtedly superb. In this film, the sense of mission to save children and the future of mankind, as well as the deep affection between father and daughter for each other, constitute a classic drama conflict of unity of opposites, which almost always serves as the driving force for the protagonist to promote the plot. The three-act propaganda of this film is inseparable from emotional clues. At the beginning, the life of father and daughter first paved the way for their feelings and necessary bedding. Cooper is a former NASA pilot. He used to support his family as a farmer in the deteriorating ecological environment, living with his father-in-law, a son and a daughter, especially with Murphy, a strange daughter. Inspired by the supernatural existence of "ghosts" in their daughter's room, Cooper's father and daughter discovered NASA and their secret plans. Cooper accepted Professor Brand's task, and his main motivation was still to protect his children and their future, but his daughter didn't approve. Cooper's departure broke the harmonious relationship between father and daughter, and the communication between them gradually disappeared with the insurmountable distance between father and daughter in time and space. They are separated in space and emotion.
