By making this film, Steven Spielberg proved that he is one of the most important directors in history and is much better than the directors of his time such as James Cameroon, Chris Nolan, Richard Linklater, etc. And is several steps ahead in filmmaking. In today's cinema, a filmmaker is very dependent on a very specific idea or a very specific technology or special visual effects or amazing production. Like James Cameroon, who waits for years to make a sci-fi film until the special visual effects reach a breakthrough and make his film. Or Chris Nolan, whose many films depend on a series of enigmatic ideas and thoughts, that's why he makes a film every three years. But Spielberg teaches them filmmaking and makes a masterpiece out of nothing that can be admired in any situation. Spielberg made his life the basis of a film to say to the proud and dependent directors of today: I was able to make a film without having a special script or idea and without having amazing special effects, which is more love than all your films. And is more valuable.
