It is said that after watching "Interstellar", there was no standing ovation from the audience, because the audience was kneeling, half because they felt that the film was a god's work, and half because they did not understand it.

Although this description is exaggerated, it vividly reflects the polarization feelings of the audience after watching the film. Compared with the simplicity of most movies, Nolan's films have always been deeply interpreted by fans from all angles, whether it is the appearance of stories, special effects, actors and other films, or from the more professional categories of physics, astronomy, philosophy, and even theology, a movie can trigger a hundred flowers and a hundred schools of thought in all walks of life, but it is also a major event to promote the progress of social science.
In fact, as the poem quoted in the film: "don't go gentle into that good night", we should not be too gentle into this film, after all, this is an extremely cruel story, an old scientist devoted his life to a basically never-return outer space program, sending retired elite pilots, as well as their own daughters, into the flight module. Embarked on their desperate journey full of hope.
The play should be viewed from two sides, on the one hand, it is a scientific presentation based on cosmic theories such as wormholes, black holes and multidimensional space, and on the other hand, it is based on the emotional presentation of family, growth and the passage of time.
From a scientific point of view, since there are many doubts and blind spots in our exploration of outer space and even the exploration of the sphere where we are located, it is not to mention how accurately a film can meet the competition from various theories, although Nolan has also invited professional scientists to check the technical level of the film, he can only do his best to reduce the appearance of bugs and reduce the appearance of low-grade common sense errors, because this is after all a commercial film, not a pure academic work.
From an emotional point of view, this film uses a science fiction story, wrapped in two pairs of father-daughter affection, one pair is the protagonist Cooper and his daughter's "amazing fate", the director here is playing time and space travel and time distortion, in fact, with reference to the endless space travel of the film and television drama, such as "Contact the Future", such as "Lost in Space", such as "Star Trek", such as the "Gravity" just screened, etc., of course, there is a grandmaster-level "2001 Odyssey in Space", will find a lot of similarities, What is about time is either to go back to the past or to travel to the future, and travelers and earthlings also have a relativity of time.
In "Interstellar", returning to the past and returning to the future are both two situations, the protagonist Cooper because of the journey of time and space, and then return to the earth, his daughter has reached the old age, but in his journey, in fact, once returned to his past, and in a special way, as a future person, as a future person, to the daughter of the current world and the current world's self to send a signal. Of course, this kind of putting the fate of a world on the accidental discovery of a little girl, and relying on the girl to be able to decipher the seemingly bizarre code, is itself a gamble with no chance of winning, but the directors can always let them guess the mystery like a prophet.
It is not too much to say that this film is about two pairs of father-daughter love, no matter how boundless and vast the outer packaging of the story is, but the foothold of emotion is indeed an unchanging body, watching the birth and death of blood relatives and friends, long lives, converged into a short image, so far, all the seven passions and six desires born of people, joys and sorrows, almost all disappeared. Although the Chinese emotion is not as exaggerated as a song of "one eye for a thousand years", it is at least a glance at this life, and the past is like smoke.
In fact, each of us is a boat in this vast ocean of time and space, just like Cooper they fly in the vast universe, the huge sense of loneliness when watching the movie, in the moment when the curtain lights on, see the crowd around us, see the crowd on the street, it is a kind of happiness after the disaster. Using a more tragic story than yourself to find a stronger sense of happiness, from this point of view, the greatest value of "Interstellar" is the soothing of the soul.
